It’s becoming common to refer to the devices used for dimensional and coordinate measurement—vision/optics, lasers, touch probes, and others—as sensors. Multisensor measuring systems use two or more of these devices. It can be confusing because none of these “sensors” is actually a sensor. The…

What’s a datum reference frame?
As discussed in workshop No. 5, datum reference frames (DRF) are coordinate systems, and preferably—at least to start with—Cartesian coordinate systems.
As we know, coordinate systems serve to orient and locate objects, and in the world of GD&T in particular…

Recently I became aware that the ISO 9001 requirements pertaining to preventive action are sometimes referred to as the “fortune-telling clause.” The deprecating implication is that attempting to implement preventive actions is as silly as relying on a two-bit sideshow palm reader to help you make…

As a manager, one might imagine being a rider atop a horse. You cannot expect to force the horse to win by constantly pulling the reins, neither can you expect to win the race consistently by pushing the horse beyond its capability. The rider needs to influence its performance to win the race;…

Powerful brands can drive success in competitive markets and become the organization’s most valuable assets. Wikipedia suggests that, “Brands were originally developed as labels of ownership: name, term, design, and symbol.” Today, how brands reflect and engage people and how they define people’s…

Advancing into that mystical category of “senior citizen” brings with it certain perks. Simultaneously becoming a senior citizen, retiring, and joining the ranks of Social Security recipients is a financial trifecta.I retired in 2003, and when I made that phone call to add my name to the millions…

Accounting techniques such as budgeting, sales projections, and financial reporting are supposed to help prevent business failures by giving managers realistic plans to guide their actions and feedback on their progress. In other words, they’re supposed to leaven entrepreneurial optimism with green…

In Part 1 of this article I discussed Six Sigma failures and the fundamental flaws in the term Six Sigma, as seen in figure 1 below, which highlights the flaws in the hundreds of Six Sigma web sites displaying the nonsense of out-of-control processes that are the result of the claimed “unavoidable…

Each year at this time a momentous event is announced in the pages of a prominent magazine. No, I’m not talking about the Sports Illustrated swimsuit edition, although thoughts of that warm me up on frigid evenings in Michigan (sorry if that’s sexist). I’m referring to Fortune Magazine’s…

In today’s quality management systems, the ability to control and correct processes is key to maintaining a high level of compliance within an organization. Whether it’s tracking incoming customer complaints, identifying nonconforming materials from production, or using corrective and preventive…

I was hiking in the Smoky Mountains National Park with a colleague, and we happened upon fellow hikers. Being the friendly sorts that we are, we stopped to take a breather and chat with our new female friends. We enjoyed resting and speaking with the women until my friend Bob smiled and asked one…

Welcome to the second issue of CMSC World—the place to catch up on the latest happenings in portable 3-D metrology and imaging. This is the official newsletter of the Coordinate Metrology Society, and once again we are gearing up for our Coordinate Metrology Systems Conference—“the” conference…

At rare moments, an idea comes along that makes people rethink how jobs are done from that point on. The engineers at Falk PLI Engineering & Surveying have hit on such an idea for one of the most basic concepts of all: measuring.
The larger-than-life nature of steelmaking would seem to belie…
With the ever-growing demands of energy, the demands on high value-added vessels, such as container vessels, liquefied natural gas (LNG) carriers, and crude oil carriers, have skyrocketed in recent years. As of 2006, shipbuilding orders received by South Korean shipbuilders accounted for 42…

Last month, I described a simple problem to determine which gear material resulted in longer wear. We reviewed the extremely powerful technique called Analysis of Variance (ANOVA) and found a statistically significant and important effect on the average wear due to gear material. I also…

In the first quarter of 2007, my company conducted a complex-manufacturing research survey of 1,473 senior management level executives (CEO, COO, CFO, vice-president of operations). Complex manufacturers were defined as those employing “other than exclusively repetitive manufacturing processes”…

How much is a kilogram?
It turns out that nobody can say for sure, at least not in a way that won’t change ever so slightly over time. The official kilogram—a cylinder cast 118 years ago from platinum and iridium and known as the international prototype kilogram or “Le Gran K”—has been losing…

As we know, GD&T is a symbolic language with which to specify permissible limits of imperfection in manufactured parts, namely limits that maximize the parts’ operability, assemblability, and affordability. It’s complex only to the extent that the real world of imperfect geometry is complex. If…

In dimensional measurement it isn’t unusual to measure feature locations relative to reference edges. How one measures an edge depends on how we define it. So what exactly is an edge? Basic edges Back when people thought the world was flat, they feared that explorers who ventured out to sea might…

Every once in a while, when I’m doing an audit someone will ask me—in a whiney voice—about some ISO 9001 requirement. The whine sounds something like, “Do we really have to ________?” Fill in the blank with any of a number of “shalls” from the standard. They know they have to, but they’re hoping…

As is the case with any lean implementation in a traditional environment, culture change is the most difficult obstacle to success. A company can hire consultants, develop work teams, and begin lean initiatives, but if it only talks the talk, the initiative soon becomes just talk.
