Available On-Demand Cognitive Biases and Project Planning Cognitive biases are more common than we imagine, even among folks who are technically well-trained and competent. These can lead to misreading data and faults in project planning. Deming’s Seven Deadly Diseases of Management W. Edwards Deming’s “14 Points” express his philosophy of management. Specifically, they break down the need for a working understanding of basic quality management system statistical principles. In addition to the 14 points, Deming outlined seven deadly diseases that describe the most serious barriers that management potentially faces within an organization. Increasing Process Profitability through Insight from Visual Management Kaizen, lean manufacturing, Six Sigma, total quality management, continuous improvement—all of these terms refer, in some form or another, to the efforts of companies as they strive to become more competitive in a global economy.

NUMBERS
CONTEXT AND ANALYSIS ARE KEY TO THEIR UNDERSTANDING.
I
If this were TV or radio, this is when you would hear the theme song from “Jeopardy,” but since this is print, I’ll just ask, “Do you have it?” It’s the number 194. This is just one example of “numerous” number riddles. They are designed to test logic and, in many cases, trick the mind. To a lesser extent, these riddles remind me of those middle school word problems. You remember them. They usually start out with a train leaving Chicago traveling to Philadelphia at 60 mph, another leaving Philadelphia bound for Chicago at the same time traveling 80 mph and a question asking which of the trains will arrive at its destination first. The problem also will tell the reader how far these cities are from one another, but invariably the problem also will contain information that is of no concern to the question. The folks who design these questions are not necessarily trying to trick the reader, but focus attention on context—what matters to the question.

Context and focus. They are a major tenant of logic. A pile of numbers is just that, a pile. Without context and analysis, they mean nothing. The information that doesn’t matter to the task at hand is just noise. But we take this pile and give it context and analyze what it means and we gain knowledge. And knowledge is power. So, I invite you to feel powerful about the subject of leadership with the analysis of Quality’s Leadership 100 Survey and how good data means good decisions with this month’s Quality feature article, "Good Data = Good Decisions." In addition, this month’s Quality Innovation discusses software that easily compiles data and automatically transforms the data into well-known chart formats for easy analysis. As always, enjoy and thanks for reading!

AIRBUS DELIVERS 7,000TH AIRCRAFT TOULOUSE, FRANCE—Airbus’ delivery of its 7,000th aircraft in December 2011 marked a new achievement as the company continues to accelerate the production output of its single-aisle and widebody jetliners in meeting demand from a widening global customer base. This delivery was a member of the A320 Family, which is one of the world’s best-selling commercial aircraft product lines—with more than 4,900 provided from the more than 8,250 ordered by 340-plus customers around the globe. The other Airbus aircraft contributing to this delivery milestone were its cornerstone medium-haul A300 and A310, of which 816 were supplied during its successful production run; the long-range A330 and A340, with 1,200-plus provided through the end of November 2011, along with the more than 60 very large A380 jetliners received by airlines through early December 2011. Overall, Airbus’ production output has been increasing since the company handed over its first aircraft in May 1974: an A300B2. In March 1993, the 1,000th delivery landmark occurred with an A340-300, followed by the 2,000th handover in May 1999, which also was an A340-300. Underscoring its rapid growth with an expanded aircraft family, the 3,000th Airbus aircraft delivery was an A320 provided in July 2002, while only three years later—in September 2005— an A330-300 became the 4,000th aircraft supplied to a customer. Just two years afterward, the 5,000th milestone was achieved in December 2007 with an A330-200. The 6,000th
delivery in January 2010—involving an A380—further confirmed the company’s continued leading role as a provider of highly efficient aircraft to airline operators and customers around the world. For the 7,000th jetliner handover in December 2011, the aircraft was an A321 provided to United States-based US Airways, which is one of Airbus’ biggest single airline clients, and also has the distinction of flying the largest A320 family inventory of any carrier.
THE SNAKE RETURNS TO CHRYSLER GROUP’S CONNER AVENUE ASSEMBLY PLANT AUBURN HILLS, MI—Chrysler Group LLC will reopen its Conner Avenue Assembly Plant in Detroit for the production of the next generation SRT Viper. With the plant’s reopening, nearly 150 jobs, both hourly and salaried, will return to the city of Detroit. The Conner facility was idled when production of the Dodge Viper ended in July 2010. “The next generation Viper will make its return to the product lineup in late 2012 as a 2013 model,” says Ralph Gilles, president and CEO, SRT Brand and Motorsports, Chrysler Group LLC. “We’re extremely excited that our ultimate American sports car will continue to live on and be produced exclusively here in the Motor City.” Current Chrysler Group hourly employees who previously worked at Conner were first offered the opportunity to return to their home plant. The balance of the positions will be filled by hourly employees volunteering to transfer to the Conner Avenue plant. Conner Avenue will begin building the new Viper in late 2012, but employ-

ees began reporting for training and orientation in the fall of 2011. In preparation for the reopening, the Conner facility will begin its transformation by implementing worldclass manufacturing, a system that is focused on reducing waste and making continuous improvements throughout the assembly process to improve quality and productivity. The Conner Avenue Assembly Plant was built in 1966 and purchased by Chrysler in 1995. Viper production began in May 1992 at the New Mack Assembly Plant and was moved to Conner Avenue in October 1995. Prowler production began in May 1997 and ended in February 2002. Viper V-10 engine production was transferred from Mound Road Engine to Conner
Assembly in May 2001. In 2003, the newly engineered SRT10 Roadster hit the market and the SRT10 Coupe followed in 2005. With a production run of 28,056, Viper production ended on July 2, 2010. As a result, the facility was idled.

These machines and devices are the equipment that turn raw materials such as steel, iron, plastic, ceramics, composites and alloys from their original state as stock materials into what will become durable goods such as airplanes, cars and appliances, as well as consumer and other goods that are used every day.” The Midwest and central regions of the United States have seen the great-

2010—was powered by the growth in the energy business and secondly by the automotive industry. “The factors that are fueling this tremendous surge are the traditional reasons that drive growth in investment, but what is unusual about the current rebound is that all factors have come together at one time. This is something that’s never been seen before,” McGibbon notes. “American manufacturers are still rushing to beat the end-of-year bonus depreciation deadline,” he continues. “Inventories were low—something we’ve never experienced going into a recession—and that accounts for the quick rebound. Exports are rising as American manufacturers meet overseas demand. Manufacturing technology from the United States is less expensive than foreign equipment, and U.S.-made goods are more price competitive than many imports due to the weak dollar.” The average age of machinery currently in use at U.S. manufacturing facilities crept up from nine years in 2007 to 13.5 years, and as demand started to increase the need for investment to replace the aging equipment became apparent. Those investments are being made in completely new technology. Multi-operation machines are profoundly impacting productivity. Water jet cutting and hydroforming are experiencing massive growth because they offer all the benefits of traditional processes but eliminate distortion and deformation. Additive manufacturing is growing, nano machining has become commercially affordable, and the availability of new materials, such as compact powdered metals, is having a tremendous impact. Plus, the emergence of cloud manufacturing, which promotes collaborative efforts across organizations, is opening new doors to manufacturers. Expanding markets worldwide are playing an important role as manufacturing grows. China seems insatiable and accounts for almost one half of the world’s total consumption of manufacturing technology. India’s economy is growing at double the Western economy’s rate, with expectations for more China-like development soon. As it prepares for major world events including the Olympics and the FIFA World Cup competition, South America faces the challenge

NEWS of building infrastructure that can support the events. Russia, South Africa, the Middle East and South Asia are on the fringe, but nevertheless contribute to growth in the global manufacturing economy. Another factor boosting U.S. manufacturing is onshoring. More work is coming back to the United States from foreign shores, and there is greater foreign direct investment in U.S. facili-
ties. Why? The quality of work in the United States is proving to be more valuable than originally thought in the off-shoring investment calculation. Companies face increasing costs in logistics issues with the delivery of components and the exporting of completed products to North America. Add to that the rapidly increasing labor costs in traditionally “low-cost” labor markets, and the continued decline

NANTERRE, FRANCE and AUBURN HILLS, MI—Faurecia, the world’s sixth-largest automotive supplier, was awarded top honors from the Automotive Division of the Society of Plastics Engineers (SPE) for Faurecia Interior Systems’ work with Ford Motor Co. on the 2012 Ford Escape compact SUV & Kuga compact CUV. The companies earned SPE’s Grand Awards for Process/Assembly/Enabling Technologies and the overall Most Innovative Use of Automotive Plastics in 2011. The awards were presented during SPE’s 41st Annual Innovation
www.qualitymag.com
Awards Competition and Gala in November 2011. “This MuCell instrument panel is the largest automotive component molded in the patented MuCell injection-molded process, as well as the first instrument panel to be molded in this process, a tremendous achievement for Faurecia and Ford,” says Jean-Michel Renaudie, president of Faurecia Interior Systems, North America. “In an industry that is highly impacted by volatile gas prices and stricter regulations, every ounce saved on a vehicle makes a difference. This process has enabled us to remove more than one pound of weight from the vehicle and save time on production.” MuCell involves the addition of a gas into the molded part during the injection process, which reduces the overall weight of the part because less plastic is used, while still maintaining the performance of the finished part. This helps Ford meet vehicle weightreduction targets, which in turn helps improve overall gas mileage. Faurecia also received the Safety Innovation Award for its Reinforced Airbag Lid in Foam (RALF) featured on the global 2011 Ford Focus compact car. RALF enables vehicle designers and stylists more design freedom around the instrument panel (IP) without compromising consumer comfort and safety. Faurecia’s innovative RALF technology eliminates the need to provide room for a hard-cover airbag lid to open without damaging the windshield, providing the flexibility to help designers better apply their creativity to the IP’s design, function and space. The SPE Automotive Innovation Awards Competition started in 1970 to recognize the positive changes that polymeric materials were bringing to the automotive industry, such as weight reduction, parts consolidation and enhanced aesthetics and design freedom. SPE’s Automotive Innovation Awards program is the oldest and largest competition of its kind in the automotive and plastics industries.

Data from CAR indicate total employment of the Detroit Three automakers will increase from today’s 171,000 to 201,000 by 2015 and that
auto-industry suppliers will need to add from 100,000 to 150,000 new workers over the same period. But the research group’s projected 2015 total employment figure for the Detroit automakers still pales in comparison to the industry’s heyday.

Nissan and Daimler will produce Mercedes-Benz 4-cylinder gasoline engines together at Nissan’s powertrain assembly plant in Decherd, TN. Production will begin in 2014, with installed capacity of 250,000 units per year once full ramp-up is achieved. The Decherd facility will produce engines for Mercedes-Benz and Infiniti models. “This is the newest milestone in our pragmatic collaboration and our most significant project outside of Europe so far,” says Renault-Nissan CEO Carlos Ghosn. “Localized capacity reduces exposure to foreign exchange rates while rapidly enabling a good business development in North America, a winwin for the Alliance and Daimler.” The collaboration marks the first production of Mercedes-Benz engines in the North America Free Trade region. The Tennessee plant’s strategic location and logistics links ensure a direct supply of engines starting in 2014 for the Mercedes-Benz C-Class, built at Daimler’s vehicle plant in Tuscaloosa, AL. “In the context of our MercedesBenz 2020 growth strategy, we have decided that we will expand the production capacities required for this close to the customers,” says Dr. Dieter Zetsche, chairman of the Daimler Board of Management and head of Mercedes-Benz Cars. “Through the strategic extension of our cooperation with Renault-Nissan, we can realize near-market engine production in the NAFTA region on attractive economic terms and make optimum use of synergies arising from the cooperation.” Nissan began powertrain assembly in Decherd in 1997. Today it manufactures 4-, 6- and 8-cylinder engines for the complete lineup of U.S.-produced Nissan and Infiniti vehicles. The plant also houses crankshaft forging and cylinder block casting operations. In 2011, Decherd produced more than 580,000 engines on a covered area of more than 1.2 million square feet.

THE VITAL FEW, PART II IMPROVE PERFORMANCE AND IMPROVE QUALITY.
I
n last month’s column five tips were given for organizations and their quality professionals to consider focusing on to bring about positive results. Together, with these additional five tips, organizations will be well positioned to improve performance and improve quality.
JIM L. SMITH
6. Cost of poor quality (COPQ) must be known and managed. Most organizations have no idea of their total cost of poor quality. The cost of poor quality is defined as the costs that would disappear if systems, processes and products were perfect. There are few things that are perfect so every organization has a COPQ but precious few spend little time in trying to identify their COPQ. Dr. Juran and Philip Crosby said that the total COPQ can be as much as 25% to 30% of the cost of sales. Staggering! So why aren’t managers challenging their organizations to identify their COPQ and develop plans to improve? I don’t know the answer but most aren’t. This is hard to understand when every dollar of their COPQ saved goes straight to the bottom line. A couple years ago I spent time with a company that focused their entire continuous improvement efforts at the work team level. Their primary tool was a COPQ analysis worksheet to identify areas of waste. Everyone was trained, involved and worked toward reducing their COPQ. The result was sustained, and real improvement was pulled through to the bottom line. Quality improved, costs were reduced and jobs added in a competitive market. Everyone won. 7. Real improvement doesn’t center on hard assets. Organizations should determine where to focus their improvement efforts to get the greatest return. Typically, the tendency is to focus on hard assets. However, rather than just focusing on equipment and other hard assets, organizations would do well to put their continuous improvement initiatives toward people and processes. Organizations should implement disciplined dayto-day areas of review. In today’s lean manufacturing environment that effort would be part of the visual factory. Organizations should implement daily performance reviews to not miss opportunities for basic skills coaching, reinforcement and providing real-time feedback to and from the worker floor. 8. Enhance employee worth. Real, sustainable change can only happen in an environment where workers, supervisors and managers have real-time visibility into production performance, reduced

administrative burden, and a structure that allows people to contribute their own ideas and turn them into actions. When employees feel valued and appreciated, they openly embrace their tasks with maturity and ownership. The key is to create an atmosphere of openness in a trusting climate that shows employees they have worth and value. To support this environment, organizations should implement an appropriate reward and recognition process that will translate into an empowered workforce. These actions will be responsible for releasing an explosion of creative solutions which will produce exponential results. 9. Focus on action. Don’t procrastinate. Decide the path that will achieve real improvement and focus on the implementation plan. With any performance improvement initiative momentum is key, and quick wins provide the fuel needed to gain momentum early on. Early successes ensure that the organization’s focus remains fixed on the true goals: higher quality with lower operating cost is the target, but don’t confuse the two as they are not always complementary. The proper resources need to be dedicated to making it happen. Too often organizations have great plans to create change but too few resources are actually committed and the result is less than satisfactory. 10. Expedite improvements. Many organizations take too long to implement major improvements and the efforts stall. Don’t assume that transformational improvements will take months or years to implement. Results can occur in a relatively short time if organizations enlist the help of their entire workforce, properly deploy effective resources, create meaningful metrics and focus on technology that will support the improvement effort. Don’t be unreasonable but challenge the current thinking and spend time “out of the box” for a new perspective. Think days or weeks, not years. Quality professionals are positioned to help their organizations focus on the vital few initiatives. The roadmap to success has been laid by Deming and Juran. Let’s be an integral part of the transformation and be the beacon to light the way. Jim L.

DOES NEW STUFF
HAVE TO BE CALIBRATED? CALIBRATION ENSURES THE NEW STUFF IS GOOD.
D
oes new stuff have to be calibrated? The short answer to the question is “yes,” so you don’t have to read further unless you want to know why. The technical term “new stuff ” refers to new, unused gages and instruments. The main question leads to another thought. If the stuff is new, it has to be good or suppliers wouldn’t ship it—would HILL COX they? This comment suggests that the supplier actually checked your stuff before shipping, which is not always the case. It also assumes that the reliability of this inspection is good, which is not always the case either. Many makers of gages and measuring instruments include a piece of paper with each item which claims the items have been inspected. But the value collapses when the same piece of paper says that if the buyer finds the instruments to be incorrect, the supplier’s liability is limited to repair or replacement of the defective item. If the stuff is new, Being linguistically it has to be good or suppliers challenged, I assume that if the items have wouldn’t ship it—would they? been calibrated by their “highly skilled technicians,’’ there won’t be anything wrong with them. But, alas, my assumption is incorrect. Too many people accept these bits of paper as if they were as good as a calibration report. The fact that they don’t cost the buyer anything indicates what they are worth. So the answer to our primary question is followed by another question: What is going on here anyway? The answer to that question is: Not what you’d think. In a perfect world, finished gages must pass final calibration by someone other than the person who made them. This provides independent confirmation that the gages meet specifications. In our world, this is becoming an exception rather than the rule it used to be. Cost cutting is the reason this important final check is being omitted by many gage makers. And, this is done to try and meet the never-ending demands for lower prices by those gage users who consider a gage as little more than another lump of steel. If the gage maker, or their sales agent, doesn’t provide this check, the gage user is left to discover mistakes or errors the hard way. When this occurs, price is no longer the overriding preoccupation of the buyer.
18
QUALITY | February 2012
Smart gage buyers get new gages checked by their own laboratory or a competent outside facility to avoid these problems, or they pay for a proper calibration report from the gage maker. Accounting 101 will explain that savings on the purchase price will be offset by the cost of “final” calibration, if accuracy is to be ensured. New measuring instruments are frequently used out of the box, usually with few problems, but when problems arise, they can be just as expensive as fixed limit gages. Setting masters supplied with the instrument often are found not to be as advertised, which can create mayhem for all. Since many instruments are made off-shore by unknown companies, you can never be certain what you’re getting, irrespective of what brand name they carry in this market. While some makers shouldn’t be in business, most problems arise because the maker is producing instruments to the standards of a different country, and the American importer either doesn’t know this or does but simply neglects to pass this information along. Often the foreign standard allows errors that are much higher than what the equivalent U.S. standard permits. There is nothing wrong with this, providing the buyer is aware of the situation. Usually they are not. Interchangeable anvils, rods and other devices may have settings that are incorrect and will never be found until the instruments are calibrated. Distributors may have mixed up these items from one set with those of another without realizing the implications of doing so. Similar problems arise with lever-type test indicators when contact points from one model are mixed up with those belonging to another model. While the electronics on popular instruments are of a high standard today, not all of them are. Occasionally intermittent defects occur and may cause a lot of rejects until they are found. The only way to avoid having these troublesome situations is to know that every gage or instrument entering your operations is good on the way in. And the only way to know that is to confirm it through calibration. Hill Cox president of Frank J. Cox Sales Ltd. (Brampton, Ontario, Canada). He may be reached at

uppose you operate a company with two lines of business—a service business such as Six Sigma consulting, and a manufacturing business such as precision instruments. They have different customers, growth prospects, reinvestment needs, returns on capital and cash flow characteristics. They face different types of risks. BRYAN L. In the 9th of his 14 points, W.E. Deming taught BERSON ESQ. managers to break down barriers among staff areas. In the example above, the units are distinct divisions in a conglomerate. For organizational and practical purposes, good management would separate them. In the event of a lawsuit, formal separation would prevent liability from spilling over into the other division. Management can determine which unit earns a higher rate of return on invested capital and which is the better choice for reinvestment. Perhaps, management will decide In the 9th of his 14 points, that one division should W.E. Deming taught managers be spun off. How can management to break down barriers achieve this artificial among staff areas. separation? Good legal structuring techniques and corporate governance can handle this. Most businesses choose between forming a corporation and a limited liability company (LLC). To make an informed choice, professionals require a basic understanding of the differences between the two types of entities. Corporations have been part of American business for centuries. They are chartered under state law and owned by shareholders. LLCs have been around only since 1977. They tend to be more flexible and have fewer formalities than corporations do. The owners of LLCs are called members. • Limited liability. Entrepreneurs form entities primarily to have limited liability. When people operate a business without an entity, they are sole proprietors. By forming a corporation or LLC and obeying the proper legal formalities, owners are relieved from personal responsibility for company debts and obligations. • Control. Corporations and LLCs differ with respect to how owners exercise control over their ownership interests. Corporate shareholders elect a board of directors that hires management. In large corporations, shareholders tend to be uninvolved in managerial decisions. In small closely held corporations, the same
20
QUALITY | February 2012
individuals tend to be shareholders, directors and managers. In LLCs, one or more members can manage the company, or they can hire an outside manager. • Transferability of interests. Very large companies tend to be structured as corporations. The structure enables them to more easily raise capital and transfer ownership interests. Unless the shareholders voluntarily contract to not sell or transfer their shares, they can do so, albeit securities laws may apply. With respect to LLCs, members can freely transfer the financial rights attributable to their shares. On the other hand, their rights to transfer managerial and voting rights are usually restricted. State law and operating agreements often require remaining members to consent for an assignee or purchaser to become a full member. • Continuity. Corporations and LLCs exist in perpetuity. They survive the bankruptcy, retirement and deaths of their owners. Sole proprietorships die with the owner. • Taxation. Most entity choice decisions are driven largely by tax considerations. Thus, before choosing an entity, an entrepreneur or manager should consult with an accountant or tax professional who has experience with small businesses. Regular corporations (C corporations) are separate legal entities. They file tax returns and pay taxes. Dividends paid to shareholders are taxed as well. This “double taxation” can be avoided if the corporation is eligible and elects to be taxed as an S corporation. An S corporation is a “pass-through entity.” It files informational returns with tax authorities but does not pay taxes. Rather, its shareholders report the profit or loss on their personal tax returns. Some corporations are ineligible to be S corporations. Sometimes, it does not make practical sense to become one and deal with the legal restrictions. LLCs, like S corporations and partnerships, also are pass-through entities. Where the member is an individual, he is taxed like a sole proprietor. Where the member is a corporate owner, the LLC is treated like a division of the parent company.

GD&T WORKSHOP
THE PERFECT
IMAGINARY WORLD OF GD&T Discover the important components of the perfect imaginary world of GD&T. BY BILL TANDLER
L
et’s start with a definition. Geometric dimensioning and tolerancing (GD&T) is a symbolic language with which to manage imperfect geometry perfectly, that is, with which to impose fault tolerant, permissible limits of imperfection, which guarantee the assembly and operation of manufactured parts and keep costs down. In order to manage imperfect geometry perfectly, we need a set of perfect tools and a perfect language beholden to perfect rules with which to implement them. The most important components of the perfect imaginary world of GD&T are tolerance zones, tolerance values, datums, datum reference frames, basic dimensions and a symbolic language.
1
Tolerance zones. Tolerance zones are perfect, imaginary bounded regions of space within which a particular feature component is required to lie. As shown in Figure 1, tolerance zones come in many shapes, of which
Tolerance Zone Shape: tube-like
the most important are cylindrical, tube-like, slab-like and skin-like. Cylindrical zones, for example, as defined by the position tool, normally serve to constrain the orientation and location of a perfectly straight axis, but also can constrain the straightness of a potentially bent median line. Tube-like zones can set upper and lower limits on the size as well as the form of a bore using the diameter or the surface profile tool. If we impose a constant wall thickness but allow a tube-like zone to expand and contract in order to accommodate changes in the size of a bore, it serves only to constrain its form, namely its cylindricity. Slab-like zones, on the other hand, can be used to limit the flatness and the orientation and the location of a planar surface using the surface profile tool, or can serve to orient and locate the midplane of a slot using the position tool. Finally, compound curved skin-like zones defined by the surface profile tool, can control the size, form, orientation and

location of compound curved surfaces, such as an automobile fender. Tolerance zones are form-perfect by definition.
2
Tolerance values. The next most important component of the perfect imaginary world of GD&T is the tolerance value, which specifies the size of a tolerance zone. As shown in Figure 1, in the case of the cylindrical zone, the tolerance value defines its diameter. In the case of the tube-like zone, the tolerance value defines the wall thickness; in the case of the slab-like zone, the thickness of the slab; and in the case of the skin-like zone, the thickness of the skin. Just like tolerance zones, tolerance values are also perfect.
3
Datums. By merely defining the size and form of a skin-like tolerance zone, we can control the size and form of a feature. But if we could also orient and locate the zone, we could control the feature’s orientation and location as well. We always control the orientations and location of geometric entities using a coordinate system, but the question then arises, what coordinate system? Thus, coordinate systems have to be established, and the tools for doing so are called datums, namely the perfect, imaginary reference points, lines and planes we extract from the datum features of a machine part. Figure 2 illustrates the six alternative datums we will need, namely a stand-alone point, line or plane, a point-on-a-line, a line-in-a-plane and a point-on-a-linein-a-plane, each of which constrains a different set of degrees of freedom.
4
Coordinate systems. Coordinate systems consist of three perfectly straight, mutually perpendicular axes [x], [y] and [z], which intersect to create an origin [xyz], and which act in pairs to form three perfectly flat, mutually perpendicular base-planes [xy], [yz] and [zx]. With a set of datums in hand, we can constrain the six degrees of freedom of a coordinate system—namely pitch, yaw, roll and translation in x, y and z. By outfitting the axes with linear scales, we can provide a complete frame of reference with which to orient and locate tolerance zones. Because they are established using datums, said coordinate systems are referred to as datum reference frames. (See Figure 3.)
www.qualitymag.com
5
Basic dimensions. After we have established a datum reference frame, we need a way to orient and locate tolerance zones relative to them. In order to clearly differentiate between the toleranced nominal dimensions we use for size control, and the fixed dimensions we reserve for orienting and locating tolerance zones, we place the latter inside rectangular frames and refer to them as “basic.” In Figure 4, we see a cylindrical tolerance zone which has been oriented by the implied basic angle of 90 degrees relative to the XY base plane, and located by the explicit basic linear dimensions of 50 and 70 millimeters relative to the X and Y axes of the datum reference frame established using datums A, B and C.

In the end, GD&T is very simply a set of symbolic tools with which to define coordinate systems in real objects and with which to specify the shape, size, orientation and location of tolerance zones. Figure 6 illustrates a partially GD&T encoded drawing and the tolerance zone forest defined by the indicated feature control frames.

Symbolic language. Finally, in order to impose the perfect imaginary world of GD&T on imperfect real parts, we need a way to express and communicate our requirements. This is done with the symbolic language consisting of rectangular feature control frames which we stuff with geometry control tool icons like those for position and cylindricity, followed by tolerance zone shape modifiers such as the Ø symbol, followed by tolerance values, followed by tolerance zone size modifiers, namely the symbols (S), (M) and (L) associated with said tolerance values, followed by datum feature labels, namely A, B and C, finally followed by tolerance zone mobility modifiers, namely the symbols (S), (M) and (L) associated with said labels, all shown in Figure 5.

While large floor-standing machines with very large screens and manual axis control provided the best accuracy 25 years ago, improved optics, readout devices, backlighting, software/ computation systems and precisely controlled motorized work-stage travel combine to provide sophisticated,
ADVANCED SOFTWARE AND READOUTS Today’s machines are markedly different from the first shadowgraphs that could only compare projected images of the work piece to overlays for simple pass/ fail inspections. While today’s projectors can still be used for overlay or comparative purposes, an ever-increasing demand ffor quantitative data has given rise to advanced optical comparators with a wide a rrange of software and readout systems. Readouts today vary in sophistication ffrom traditional micrometer heads or iindicators to digital readouts, microproccessor displays with geometric measurement capabilities and PC-based systems. m IIn addition, an edge-detection capabiliity, which allows the system to automatically detect and measure transition m points of a profile image, has become p a common industry feature. The combined effect of these capabilities has b eessentially transformed optical projectors from comparative tools to two-axis coordinate measuring machines. Other automated features further enhance the capabilities of comparators. An operator may select a machine with manual, motorized or fully automatic operation. Fully automatic or computer numerical control (CNC) machines fitted with motors and edge-detection, allow part inspection to be completed under CNC control. Readout systems of today also are flexible because they allow for software expansion, as programs continue to add enhancements. Super fast geometric processors make it possible for some projector software to interface to computer-aided design (CAD) to simplify part programming. This capability, combined with CNC control, allows features to be measured
www.qualitymag.com
and constructed automatically with the results displayed on-screen or documented through various reporting options. QUANTITATIVE DATA To get an idea of how much data today’s comparator can extract, consider the results that can be determined by measuring the diameter of a circle: • the maximum or minimum diameter. • the average diameter based on all measurement points taken, or the mean diameter based on the high and low values (ISO). • form (out-of-roundness) shown simply on a graphical display. • tolerances also can be applied to features, be they Cartesian, true position, maximum material condition (MMC) or least material condition (LMC). UNIQUE ENHANCEMENTS Incremental improvements based on new and emerging technologies continue to extend the utility of 21st century comparators. Here are two examples: • Optical-video adapter. This technology allows optical comparators to be converted into a basic two-axis manual video measuring systems by simply interchanging the comparator lens with a camera-based, video zoom package. The optical-to-video adapter utilizes the same quick-change bayonet mount that an operator would use to change from a 10X lens to a 50X lens, with no tools required. It allows operators to obtain excellent surface illumination at substantially higher magnifications than would normally be possible with comparators. • Touch-screen control. A new readout technology, analogous in function to tablet computers, provides a broad range of powerful, easy-to-use comparator functions via a compact, icon-based touchscreen interface. They provide instant information on feature form, tolerances and measurement data; coordinate display for X and Y axes and Q radius values for screen rotation and allow for easy part alignment and datum functions at the touch of a finger.

lighting and high-resolution optics. When selecting a system, it pays to focus on these critical basics, being careful to evaluate each element of the system. That being said, modern optical projectors continue to be noncontact measurement workhorses because of
their exceptional practicality, durability versatility, and ease of use. Mark G. Arenal is general manager of the Starrett Metrology Division (Laguna Hills, CA). For more information, call (949) 348-1213, e-mail

that can be charted. There are many control chart macros and fill-in-theblank templates. “Some people try to create their own control chart templates, but use incorrect formulas and wonder why the QI Macros deliver different, more challenging results,” says Arthur. What makes QI Macros innovative, says Arthur, is that, unlike most statistical process control (SPC) packages that ask users to first select a chart and then select the data, QI Macros asks users to first select the data and then choose a chart. The advantage is that QI Macros can look at the data (integer or decimal, single- or multi-column) and decide what chart or statistic to use. “The Chart, Control Chart and Statistics Wizards make it easy for a user to get the right answer,” says Arthur. “Where [other software] asks users to navigate a decision tree in the Quality Advisor to choose a chart or statistic, the decision tree is built in to the QI Macros and does the work for you.” The software also contains fill-inthe-blank control chart dashboards that can handle hundreds of metrics. THE IDEA OF QI MACROS According to Arthur, when he left the phone company in 1996 after five years in total quality management, he knew he needed easy-to-use tools. As a quality professional and computer programmer, he noticed that Windows 95 and Excel 5.0 had a macro programming capability, so he started developing the tools for his own use. “When I discovered how easy it could be to draw a pareto chart, histogram or control chart using Excel and macros, I put together a prototype and started offering it through direct mail to members of the American Society for Quality [ASQ],” he says. Arthur called the software QI Macros because it was for quality improvement [QI] and used Excel’s macro language [Macros]. “Through endless feedback and improvement over the last 15 years, the QI Macros have evolved into a rich

pler and faster to use, and work more like the smart phones that sit in your pocket rather than the multi-ton, fixed bridge CMMs of the past. THE GREAT METROLOGY MIGRATION To understand this shift, one must first understand the driving force behind it. It is no secret that the manufacturing industry has seen nearly three million jobs eliminated the past five years or so, according to the Bureau of Labor Statistics. While many of these jobs were lost on the shop floor, many others were entire tiers of jobs charged with advanced operations such as metrology. Many auto manufacturers, for example, no longer hire experienced metrologists to perform their daily quality assurance and part measurement operations. Instead, they employ only a few to resolve high-level threats to quality.
www.qualitymag.com
Simple measurement functions do not cease simply because the hiring does. Circularity, perpendicularity, parallelism, diameter, width—these do not stop going out-of-whack because a manufacturer no longer employs dozens of trained measurement experts. Simply, quality remains a concern regardless of economic conditions. The duties of quality assurance have now been pushed down the ladder to the shop floor. On-machine and on-party inspections are commonplace in metal fabrication, automotive facilities and factories throughout the United States. WHY THE MOVE TO 3-D? Quality assurance is now in the hands of employees who perhaps have never operated a CMM before. Device manufacturers know this. So, to accommodate the shift from scientists to assemblers, portable CMM manufacturers are making their devices more user-friendly than ever. New measurement arms allow for 3-D contact and noncontact measurement of parts and machines, often without

so much as a laptop connection. In fact, the move to 3-D data capture has allowed for simplified measurements of very complicated dimensions—such
as circularity—by workers who might not have had previous experience with such things. To facilitate these measurements, portable CMM manufacturers now incorporate familiar features into their arm. Features include a touch screen, much like one would find on any of today’s smart phones, which provides a simple interface to routine measurement functions (think depth, distance, diameter, etc.) without a laptop connection. Sphere, square and line icons distinguish between the functions to clarify their purpose and remove any doubt over the feature being measured. Newer arms offer Wi-Fi, BlueTooth and other connectivity options to enable measurements at the part, rather than bringing the part to the CMM. Measurement reporting is another area that has seen rapid change. As software evolves to conform to the new needs of manufacturers, so too does the results reporting that is generated by their efforts. In the past, measurement routines were included in complicated reports that showed part dimensions as

complex numbers and measurements. Now, software packages that work with arms are equipped with advanced part-to-CAD report generation. These documents provide the operator with easy-to-understand deviations from computer-aided design (CAD), allowing for quick adjustment to manufacturing processes. Newer measurement arms offer better weight balancing, sometimes as much as 25% less strain on the operator, to reduce fatigue for the line worker who now may be required to make dozens of point measurements at a time. The incorporation of consumer technologies—touch screens, Wi-Fi and quick reporting—with industrial equipment makes measurement less daunting for the level one operator, and for some, makes the need to employ advanced metrologists a thing of the past. By simplifying the technology of measurement though, the impact is not as great as one would expect. Today, data is simpler and quicker to understand and presents inspection results in a user-friendly format. The

migration of measurement functions from the few to the many means that more parts can be measured off the line and closer to the point of manufacture than ever before. The elimination of high-level manufacturing technicians has reduced payroll and increased margins for employers, particularly as the cost for their quality assurance technologies has dropped. As the size, complexity and cost of consumer electronics are reduced, we can expect to see similar reductions in the industrial sector. As this migration occurs, expect to see functions, such as metrology, that had been reserved for very experienced operators pushed further to lower tiers of the operation. It is this sort of democratization that has led manufacturers to compete variable costs for years. Quality assurance, it seems, is the next battleground.

a few thousands of an inch, when the probe is inserted into a tapped hole, the eddy current follows the contour of the threads. In tapped holes, the analog output indicates the gap between the probe outside diameter and what is essentially the pitch diameter of the threads. TECHNOLOGIES Optical and laser based displacement sensing technologies can and have been used for thread detection. Optical sensors rely on the presence of a thread to reflect the sent beam back to a receiver, similar to how they are used in displacement sensing. If the hole is not threaded, then there is no reflectance of the sent beam. It looks to the sensor like the target is out of range. Inductive sensing technology offers some advantages over optical and laser sensing. • Inductive technology will see through oil, grease and grime, so a go/no-go check for threads presence can occur in the production line, close to the threading operation. This eliminates a bad part from incurring further costs from downstream operations. • Because it in unaffected by cutting fluids, oil mist and vapor, performance will not degrade over time from condensation collection on optical lenses. • With the probe connected to the electronics via the small coax cable, the electronics can be remotely located in a suitable environment on the production floor. This also allows for very small probes to be used. Inductive thread detection does have some application requirements. • Probe diameter will affect the sensing range, so one probe does not sense all threads. As the thread diameter increases so must the probe diameter. • The probe must be inserted into the threaded hole—or in the case of external threads, over the stud. The depth

When a probe is inserted into a drilled hole, the analog output voltage will indicate the gap between the outside diameter of the probe, and the inside diameter of the drilled hole.

In tapped holes, the analog output indicates the gap between the probe outside diameter, and what is essentially the pitch diameter of the threads. Source: Kaman Precision Products
In addition to presence, inductive sensors can also be used to detect thread depth. Adding a long range displacement sensor such as an LVDT to the insertion mechanism provides insertion depth feedback.

is not critical per se, but the repeatability of insertion depth is. This is particularly a concern when detecting thread presence in thin plate material. The insertion depth repeatability can be controlled with the design of the insertion mechanism. • The radial location of the probe in the threaded hole is similar to axial location in that it is not necessarily critical where it is, but it is critical that the probe be in the same radial location for each part being checked. As with axial insertion, radial insertion repeatability tolerance is easily controlled with the design of the insertion mechanism. • Damage to a probe is certainly a possibility with automated checking, from a broken tap to a misaligned part. Incorporating a spring-loaded probe mount in the design of the insertion mechanism will greatly reduce probe damage potential.

AVOID CONFUSION Not to be confused with inductive proximity sensors, inductive displacement sensors are very sensitive to small changes in gap between the probe and the target. Sensitivities of 100 millivolts/mil are commercially available as standard catalog items. It is this high sensitivity that allows reliable thread presence detection in both coarse and fine pitch threads, and roll formed threads, in both ferrous and nonferrous metals.

how often specific errors are likely to be made. Percent miss rate measures how often an operator can “miss” an out of specification part, sending it out to customers. Percent false alarm rate measures how often an operator can raise a false alarm, or misidentify good product as out of specification. A pass-fail gage is called an attribute gage. As in a typical GR&R study, attribute gage studies use multiple operators who repeat measurements on the same part several times. Unlike a typical study, however, the measurements are either “pass” or “fail.” All of the precautions of a typical study such as randomization and blinding should be observed. EXAMPLE Let’s take a look at an example to understand an attributes GR&R study. The background to understand the data is as follows: Acme Gasket produces gaskets for the chemical industry. These gaskets must be at least 0.450 millimeter thick, but cannot be thicker than 0.545 millimeter. Thus, any gasket with a thickness between 0.450 millimeter

and 0.545 millimeter will pass, while gaskets with thicknesses outside this range will fail. The test is performed by first passing the 25-millimeter wide gasket through a slit 0.545 millimeter high and 200 millimeter wide in an aluminum plate. If the part passes through, it is not too thick. Next the operator attempts to pass the gasket through a slit 0.450-millimeter high and 200-millimeter wide in another aluminum plate. If the gasket passes through this slit, the part is too thin. So, in order to pass, a part must pass through the first slit and fail to pass through the second. A portion of the data table is shown in the table, “Partial Data for Gasket Attribute Study.” Here is how to read the data table: • Part. Part identifier for the actual gasket being measured. • Standard. Whether the part passes (1) or fails (0) based on an independent measurement system of higher quality. (See RefValue below.) • Code. A “+” indicates all measurement of this part correctly identified it as in specification. A “-” indicates that all measurements correctly identified this part as out of specification. An x indicates that some measurements of this part were incorrect. • A, B and C. Pass (1) and fail (0) measurements for each of the operators. • RefValue.

B and 8.82% for operator C. Based on these results, the measurement system looks good for percent effectiveness, fair for percent false alarm rate (based on the worst operator result) and poor for percent miss rate (for all operators). Improving this technique will start with determining why all of the operators are passing out of specification parts—they all have a high percent miss rate. The table, “Partial Data: Misses,” includes the pertinent data. Notice that most of the miss errors are made by passing gaskets that are too thick. Examining the gage shows that it has a taper, starting at 0.5429 millimeter at one end and progressing to 0.5650 millimeter at the other end. Thus, depending on where in the 200-millimeter wide gage the 25-millimeter wide gasket is inserted, it may or may not pass through. A similar taper was discovered on the narrower gage as well. New gages were produced by the company machine shop with no measurable
and 2.08% for operators B and C. The percent false alarm rate (false alarms) is 2.94% for operator A, 0.98% for operator B and 4.90% for operator C. Based on these results, the measurement system looks good overall after correcting the taper problems with the gage. Measurement system analysis helps to judge whether an attribute gage is trustworthy meeting inspection needs. After the gage is evaluated and found to be satisfactory, the gage helps increase profitability by reducing false alarms, and increase customer satisfaction by reducing the number of misses. By performing GR&R studies before introducing any gage to production or inspection we can be assured that our decisions are based on good data. Q William D.

The consolidation began in 1983, with the assignment of the Toledo, OH, Chevrolet and the Windsor, Ontario GM of Canada transmission plants to the Hydra-Matic division. The marriage of the Hydra-Matic and GM Engine divisions in 1990 resulted in GM Powertrain. The subsequent addition of Central Foundry Division and Advance Engineering Staff in 1991 elevated Powertrain to corporate group status. In 1997, the formation of a GM global powertrain organization was announced, encompassing all of GM’s powertrain engineering and manufacturing activities outside of North America.

SUBARU OF INDIANA AUTOMOTIVE INC. Lafayette, IN Subaru of Indiana Automotive Inc. (SIA) is an Indiana-based manufacturer of the Subaru Outback, Legacy and Tribeca line of vehicles. SIA is the only Subaru auto assembly plant in the United States. SIA Associates also build the Toyota Camry through a business collaboration with Toyota. For fiscal year 2011, the company projected production of 257,000 vehicles, the largest number of vehicles produced since the plant began production in 1989. The SIA quality policy—quality is the top priority—is the cornerstone of defining SIA’s commitments of its quality expectations. This policy is displayed throughout the facility as a reminder to associates, and visitors, of SIA’s commitment to manufacturing the highest quality vehicles for customers. Specific quality objectives and targets are implemented to meet and exceed product requirements. At SIA, “our quality is what makes a Subaru a Subaru.” In 2004, SIA became the first automotive assembly plant to be zerolandfill. SIA achieved this outstanding accomplishment in May of 2004 and has remained zero landfill. SIA sends nothing from its manufacturing process to the landfill. In other words, a typical household puts more trash in the ground than SIA’s entire manufacturing facility. In 1994, SIA established a goal of being certified to the ISO 9001 quality management standard. At first, this was a requirement for selling vehicles in Germany. However, over the years the ISO 9001: 2008 quality management system had progressed into the company’s daily work structure, providing focus on the quality of all business processes, the expected outcome (product) and the need to continually improve the system to benefit the overall growth of the organization. SIA was recognized as the first North American automotive manufacturer to receive ISO 9001 certification. The commitment to quality goes beyond manufacturing. In 2003, SIA became the first automotive assembly

plant to be designated as a Backyard Wildlife Habitat by the National Wildlife Federation. SIA’s more than 800 acres serves as a home for various wildlife including white-tail deer, rabbits, Canadian Geese, Mallard Ducks, squirrels, beavers, coyote, snapping turtles, frogs, red-tail hawks, blue heron and the Bald Eagle.

QUALITY | February 2012
A BREAK WITH TRADITION To provide high-quality products that meet or exceed customer expectations, the part inspection process must be accurate and reliable. Dahms says, “As we were growing and expanding our manufacturing capabilities, we were finding that the traditional optical comparators we had been primarily using to check parts were not well suited to meet OVT’s increasing requirements.” OVT was not satisfied with the accuracy it was getting and also disliked the limitations of using overlays, also called templates or mylars. Optical comparators require overlays to allow operators to verify that parts are in tolerance. Overlays are not well suited for quick turnover jobs and present a number of problems, which include the requirement to be physically stored and managed, repeatability challenges from operator to operator, including the possibility of generating errors due to operator subjectivity. In addition, overlays can be damaged, can only be used at a single magnification and require periodic re-calibration. The accuracy of optical comparators also is often insufficient to meet today’s ever-tighter tolerances. At OVT, they are typically meeting tolerances of 0.001 inch and less. Other limitations include the fact that 30-inch optical comparators have a large footprint, taking up a lot of floor space. Also, optical comparators can only inspect parts that fit within their optical field of view. So, for example, a 10X magnification 30-inch comparator can only check parts that measure 3 inches or less against an overlay. At OVT this presented a problem. For example, when manufacturing reamers—which can be as long as 28 inches—they required a larger field of view. Dahms wanted a better way to check parts. Hearing of the success that some of his own customers, large medical
www.qualitymag.com
device and orthopaedic implant OEMs, were having with the VisionGauge digital optical comparator, Dahms looked into this instrument’s capabilities and he liked what he saw during a demonstration. This led to OVT purchasing the digital optical comparator. INCREASED PRODUCTIVITY THROUGH DIGITAL TECHNOLOGY The VisionGauge digital optical comparator, developed by VISIONx (Pointe-Claire, Quebec, Canada) and distributed in North America by Methods Machine Tools Inc. (Sudbury, MA) is a fully-digital drop-in replacement for traditional analog optical comparators. It is available with the same range of magnifications and can accommodate the same part fixtures. OVT selected a system configuration that includes 10X/20X/50X multi-mag optics capable of an accuracy of better than ±0.0001 inch and an extended 24-inch travel stage able to accommodate long parts. With this configuration, OVT can quickly and accurately inspect and measure the entire array of parts that they produce. Parts range from a submicron-based solid carbide substrate tool specifically suited for cutting cobalt chrome, titanium and stainless steel, to taper ball end mills. VisionGauge offers benefits including the ability to work directly with computer-aided design (CAD) data, eliminating all of the problems having to do with the production, storage and management of overlays. Also, the CAD overlay “tracks the part” when you move the stage, allowing parts comparison to their CAD drawing across the entire stage travel, as opposed to just within the optical field-of-view. The digital comparator can be set up so that it automatically pulls up the correct overlay when the operator scans in the barcode on the router that accompanies the parts. Also, part changeover and part settings recall can be done with a single mouse click. The system’s autoalign tool that automatically lines up the CAD data to the part in seconds. According to Dahms, “In a job we just completed, first article inspection was reduced from up to one and a half hours to only 10 to 12 minutes with the digital comparator. Since our machines aren’t running during first article inspection, every minute counts.
www.qualitymag.com
“Our recent purchase of the VisionGauge equipment has been a huge cost savings for us,” says Dahms. “The use of electronic overlay vs. Mylar overlay is extremely efficient. We are able to compare a part to its CAD data in real-time and completely automated by using the CAD auto-align and auto pass/fail tools. The results are repeatable, accurate and completely operator independent, drastically reducing our inspection times. We estimate conservatively that we have saved approximately $120,000 this year by using the digital comparator.” Documentation is improved because the VisionGauge comparator can be used to capture a high-resolution image of a part with its CAD overlay, as well capture an image showing automatically computed deviations from nominal, the auto pass/fail result and measurements of critical dimensions and annotations. This image can be time/date stamped and easily linked to job and lot numbers. The VisionGauge also can export all of its measurements, statistics and results to other applications, such as Microsoft Excel. With traditional comparators, it took two OVT operators approximately 20 minutes to change the lens. With the new digital optical comparator, lens changes are not required. Dahms says, “The ability to simultaneously have multiple electronic overlays and fixtures on the VisionGauge comparator for multiple part inspection, with no overlays or power lens changes, is extremely productive.” Due to its ease-of-use, the transition to the VisionGauge was simple and straightforward for operators. Dahms feels they are presently just scratching the surface of this machine’s capabilities. He is certain that OVT will continue to increase productivity using the VisionGauge comparator as they keep using and learning more about the system. “The addition of the state-of–the-art, easy-to-use VisionGauge digital optical comparator allowed us to substantially improve our quality control process, accuracy, reliability and throughput, which in turn will help us expand our business in demanding market sectors such as medical,” Dahms says.

Through the use of run charts and other Synergy tools, they can determine tool life and predict how many parts can run before needing to make adjustments or change out the tool. “We can budget our tool life management more accurately and effectively based on this data,” says Winfrey. Synergy has helped United Gear and Assembly in deciding whether to repair or replace equipment. “Synergy can show us if a particular machine can’t produce a particular product in a specific tolerance range. This data can then be used to justify procurement of new equipment,” Winfrey adds. In addition, Synergy helped United Gear and Assembly with its Six Sigma and continuous improvement initiatives. “In the aspects of our business where we are using Synergy, we have seen our PPM (parts per million) decrease,” says Winfrey. “On average, we have reduced our nonconformities by 20%. We also have a very low scrap rate in those applications.” Winfrey adds that Synergy also is a valuable business development tool. “I have been in meetings at the customer’s location where we are discussing a new product. Synergy gives us the ability to log into our server, show them the exact machine that would be used to produce the new product, what tolerance the machine is currently running and the capability history of that machine,” Winfrey explains. “This type of information shows the customer what they need to see before moving forward.

Quality Assurance Brings New Confidence larger aerospace parts such as bulkheads, longerons, ribs, webs, frames and keep the same CALYPSO software and ZEISS quality. In 2011 they purchased a large bridge-style CMM, a MMZ 20/50/15. The ZEISS systems have helped Jamco gain more customers with their improved quality inspection accuracy and efficiency. The CMMs allow them reach their targeted tolerances that are all within 5 ten thousandths of an inch. Their touch-trigger CMM collected about 100 points in 2 to 3 hours while the ZEISS scanning CMMs gather about 1000 points in just 1 to 2 minutes. The ZEISS systems have given Jamco the confidence in their ability to do more inspection and to measure bigger parts.
Jamco Aerospace is a manufacturer of complex, structural components typically used in the aerospace industry. In 2006 they decided they needed more efficient quality inspection equipment to stay competitive in their industry and comply with their recent ISO 9001/ AS 9100, Rev. B certifications that require significant process documentation. Their touch-trigger CMM (coordinate measuring machine) and manual gages were no longer effective. Jamco decided that a Carl Zeiss CONTURA G2 10/21/6 VAST XXT RDS with scanning technology was the best fit for their inspections. The VAST XXT RDS articulating probe is designed for measuring small features and lots of angles. The scanning technology allows them to get much more information in a shorter amount of time. They liked the CONTURA system with the VAST XXT RDS articulating probe but also wanted a larger machine to more efficiently handle

Diesel Engine Performance: Big Parts – Small Features anti-rotation interlocks to provide extremely safe operator use, and is mounted on an air flotation carriage that allows the operator to easily position multiple valve sets to the sensitive probe. Since the valve sets are repeated numerous times along the length of the head, indents are provided to easily position the head on the next set. Using easily configured MarWin software, a custom application lets the operator repeat the series of valve seat measurements with a single keystroke. The complete Mahr Federal Engineered Surface System allows users to quickly and safely make valve seat measurements, and ensure that the critical surface/contour parameters of all valve seats meet specifications.
Diesel engine components are under constant scrutiny for ways to improve their performance and effi ciency. One area of critical importance is how the intake and exhaust valves seat into the cylinder head. To avoid blow by, valve seats must be machined to precise angles and length, and finished to very tight surface/ contour parameters. The problem in making these measurements is that large cylinder heads—which can weigh 250 lbs. and run over 40 in. in length—must be manipulated quickly and precisely so that the valve seats—which are only 0.080 in. wide—are at the correct position and angle for the surface/contour probe. The solution is a specially designed Mahr Federal part rotation fixture that provides quick and balanced rotation of the parts to the required angle to match up to the sensitive probe. The fixture uses

Case Study: The Fastest, Easiest, Most Accurate Way to Compare a Part to a CAD File Using the VisionGauge® Digital Optical Comparator (Patent Pending), a major aerospace manufacturer increased inspection accuracy and throughput, eliminated operator subjectivity, freed up floor space and was able to start recording complete product documentation and part history..
• Increase accuracy: VisionGauge® is a very high resolution software-based system that works directly with the CAD data. It is much more accurate than traditional optical comparators. • Eliminate operator subjectivity: with VisionGauge®'s Auto Pass / Fail tool, there is no more operator subjectivity! • Increase throughput: VisionGauge® can be setup so that it automatically pulls up the correct overlay when the operator scans in the part's barcode. Also, part changeover and part settings recall can be done with a single mouse click. This represents a huge time savings! • Inspect parts beyond the optical field of view: with VisionGauge®, the CAD overlay "tracks the part" when you move the stage. This allows you to compare parts to their CAD data across the entire stage travel, as opposed to just within the optical field-of-view as is the case with traditional optical comparators. • Improved documentation: the VisionGauge® can be used to capture complete time/date stamped product documentation and part history. • Less floor space and portable: VisionGauge® is much smaller than traditional optical comparators and can be moved without requiring re-calibration. • Ease of use: operators can quickly and easily transition over to VisionGauge®.
A major aerospace manufacturer implemented the VisionGauge® Digital Optical Comparator and achieved significant improvements on many different fronts: • No more overlays: VisionGauge® works directly with the CAD data and completely eliminates all of the problems having to do with the production, storage and management of overlays.

Multi-Sensor Machine Replaces CMM To meet the needs of new medical customers and to stay ahead of competition, a precision plastic injection company in Santa Rosa, CA searched for a multi-sensor inspection system. They needed to measure smaller features, reduce programming time, reduce measurement time, and improve operator/programmer easeof-use compared to their CMM. The company selected the Micro-Vu Vertex 320 vision system with a 4-station touch probe kit and a 12"x12"x6" measurement capacity. The company retired its CMM within months. The company's metrologist began programming parts using Micro-Vu's InSpec Metrology Software during the first demonstration. Small holes, angles, gaps, and steps are programmed and measured in seconds. Previous "operators" become "programmers" with InSpec's point-and-click programming. Parts from multiple mold cavities are measured in a single inspection program and setup. While the Vertex measures multiple pieces, the operator completes other quality/inspection tasks. When the inspection program is complete, the operator can quickly review toleranced and exported features in a summary window. If needed, the operator can edit tools from the multi-capture cache of images.
Tools can be reviewed and edited even after parts have been removed from the stage. When the company expanded, it purchased a second Vertex. InSpec's lighting calibration ensures that programs from one machine can run on another. Also, the system price with the 2-port touch probe kit, didn't require a VP's signature. Micro-Vu Corporation was established in 1959 and is a leading manufacturer of optical comparators, video systems, and multi-sensor measurement systems. Micro-Vu machines are designed, manufactured, and assembled in the United States.

Stainless steel micro tubing – typically ranging in diameter from approximately 0.2” to 0.004” sometimes even smaller – is found in a wide variety of manufacturing applications including: medical, aerospace, energy, automotive and myriad other industries for fluid transport, dispensing, and mechanical structure. A sub-category of stainless steel micro tubing, medical/dental/hypodermic needle tubing, as the name implies, is small diameter needle stock which is hard drawn, cut and then ground to points to make hypodermic needles. With ever-tightening tolerances demanded by all parties to medical manufacturing processes, needle ID surface roughness is now commonly specified. K-Tube Corporation of Poway, California, (www.k-tube.com), the largest independent manufacturer of stainless steel micro tube in the United States, was an early adopter of measuring needle bore ID surface roughness – about 15 years ago it began engaging outside labs to make the measurements. But as interest in specifying ID roughness values continued to grow among K-Tube’s customers, (some of whom started to ask for Ra, Rq, and Rz parameters*) the company decided to attain an in-house, ID roughness measurement capability. Therefore about five years ago, the company installed a Mitutoyo Surftest SJ-400 portable
surface roughness tester capable of making as many as 36 kinds of roughness measurements satisfying the latest standards issued by ISO, DIN, ANSI, and JIS. The instrument provides a measuring resolution of 0.000125μ-m/0.005μin. and a traverse range of 800μ-m/0.032μ-in. Surface roughness is evaluated using Mitutoyo’s SURFPAK-SJ roughness analysis software program. K-Tube samples finished tube ID roughness on every production run down to 0.018” ID. To obtain measurements, samples generally 2” long are sectioned length-wise by grinding so that one-half the tube is removed leaving the other one-half undisturbed and accessible to the SJ-400 instrument’s measuring stylus. The roughness data becomes part of K-Tube’s customers’ order certification and quality records. * Roughness profile parameters: roughness average (Ra), root mean square roughness (Rq), roughness height (Rz). Roughness profiles are the finer scale surface variations that remain after form and waviness variations have been filtered out of the raw profile.

Automated Measuring Systems Speed Production and Reduce Costs As a solution, Tessy implemented ten SmartScope® video metrology systems from Optical Gaging Products (OGP®) to supplement their installed base of comparators and CMMs. As explained by Mark Towers, Director of Quality Assurance, “We use CMMs for many dimensional measurements, and SmartScope systems when parts are too flexible for touch probing, or when the parts are simply too small to probe.” Parts are mounted on custom fixtures and measured in batches on SmartScope systems. Automated measurement routines free the operator to perform other tasks. Injection molding is a continuous process with batches of parts being formed while others are measured. When the molding process drifts out of tolerance, many “bad” parts may be produced before the problem is detected. Tessy monitors its processes by sending all SmartScope measurement results to QC-Calc™ software for graphical statistical monitoring. QC-Calc presentation of SmartScope measurements allows Tessy engineers to adjust processes before out-of-tolerance parts are produced. Accurate, speedy SmartScope measurements allow Tessy to maintain quality with lower labor costs. Tessy Plastics (www.tessy.com, Elbridge NY) is a plastic injection molder that produces a mix of products for medical and consumer companies. Tessy initially relied on CMMs and optical comparators to measure molded parts to keep processes in spec. Not only was this slow, it was labor intensive. In addition, the industry trend was toward part miniaturization. Tessy needed to automate their measurement processes to speed things up, reduce labor costs, and to measure new parts too small to measure on a comparator.

If your intent is to repair the assembly and return it to the customer, the process of quoting the repair can become much more costly for you and your customer if you only use these three test modes in you evaluation and repair quote. Scienscope has solved these problems for numerous medical device manufactures by providing x-ray systems that allow the user to quickly inspect an assembly and make an informed decision in the control of a process or repair of the assembly. One manufacture was doing a visual inspection and electrical test before quoting the customer on the repair of a very expensive encapsulated assembly, by using the x-ray system for initial inspection they were able to reduce their labor costs in the evaluation phase and provide the customer with a faster and more accurate repair quote. Another manufacturer was visually inspecting over molded components and using a time consuming process of painstakingly removing the over molded materiel to revel the suspect area, x-ray inspection saved tens of thousands of dollars in overtime costs per year.

Plug Gage Set aids CMM Inspection in hidden holes Hi-precision grinding (Santa Ana CA) is a Job Shop serving the Medical and Aerospace industries. Often the inspection of aerospace parts requires cleverness as was the case with this housing of a butterfly valve. The part drawing specifies the location of a “pierce point” or where the projection of a hole in the side wall intersects the plane of the front face. This hole is vertical and located at the bottom of the part shown. Mr. Cris Rabe – Hi-precision grinding’s CNC Machining Manager couldn’t use a CMM alone as the hole is hidden inside and couldn’t be reached to probe it directly. His solution was to insert a close-fitting plug gage into the hole to project it up and through the plane of the front face. (Note that the part’s front face is not vertical, but tips back a couple of inches (50mm) at the top.) With the plug gage snugly in the hole, Mr. Rabe probes the gage with the CMM to establish its projection. Even with typically tight aerospace tolerances, no single-sized gage can possibly fit snugly in all piece parts of the production lot. To match the diameter of the hole as machined, He needs the DELTRONIC TP-25 Gage Set with 25 Class X Gage Pins incrementing in size by .0001 inches (.0025mm), so he can select the pin that just slips in with no play.

He is honored to receive the Eisenman Award and again follow in the footsteps of the senior McVaugh, who was the 1990 Eisenman Award recipient. Laboratory Testing Inc. began with a staff of 20 providing commercial nondestructive testing serv-ices in a 30,000-square-foot facility. Under Mike’s leadership, the company has significantly expanded the work force, facilities and services provided. Today, LTI is still a family-run business, but now em-ploys 125, operates out of two facilities with a total of 78,000 square feet and specializes in materials testing, specimen machining, nondestructive testing and metrology services. All operations have been computerized and state-of-the-art equipment is used throughout the facilities. When Laboratory Testing Inc. first went into business, most tests relied on a well-trained eye to in-terpret and document results. Over the last quarter century, technology has taken testing to a new level at LTI. Testing is critical in many industries such as aerospace, military, power-generation, automotive and for many other commercial businesses to assure quality materials and end products. These days, procedures and other requirements are more stringent than ever. Computerization and other advance-ments in test equipment have improved the depth of information, reliability, repeatability and documen-tation. Technology

Mistras Buys English Industrial Testing Firm TEES VALLEY, ENGLAND—An industrial testing firm could create dozens of jobs in England after being bought by a sector giant. Tees Valley, England -based Engineering Test Services (ETS) has been acquired by Princeton, NJ-based Mistras Group Inc, for an undisclosed sum. ETS presently employs 85 but could extend that by 50 following the deal. The firm, formed in the 1970s, had turnover of more than £4m ($5.2 million) during the last year and the deal is expected to help drive its future growth plans. ETS provides non destructive testing (NDT) services, meaning it uses radiography and ultrasonics to carry out tests, rather than cutting components up. It also has a division providing personnel such as in-spectors and engineers to firms. Mistras employs more than 2,700 staff in 79 offices across the globe.
Aerospace and Ultrasonic Testing Company Innovate NDT Technique MOUNTAIN VIEW, CA—EADS Innovation Works, a research and technology unit belonging to aero-space and defense group EADS, parent company of Airbus and Eurocopter, has teamed up with Norwe-gian firm DolphiTech to develop a new www.ndtmag.com
form of nondestructive testing based on ultrasonic camera in-spections. NDT is a way of screening objects—like an aircraft fuselage—and detecting damage not visible from the outside without having to destroy or break through the material. It usually involves radiogra-phy, infrared light, electromagnetism or endoscopy, but ultrasound is thought to be the best method, de-spite its high cost and difficulty to use. The 3-D ultrasonic camera, developed by DolphiTech, however, will apparently be cheaper than its predecessors and easier to operate. The firms hope their collaboration will result in a tool usable for all types of NDT applications and composite materials, not just in aerospace but for other industries too. A prototype will be available by the end of 2012. The partnership is also an important one for Dol-phiTech, providing the smaller Norwegian firm with a large market for its ultrasonic products, which
also include the world’s first ultrasonic 2-D barcode reader. (Story courtesy of www.eetimes.com)
