Three-dimensional (3-D) assembly refers to the use of high-accuracy, in-place, 3-D coordinate measurement devices for the digital assembly of parts. This process is often referred to as computer-aided manufacturing (CAM) or gaugeless manufacturing. Whatever the name, 3-D assembly is replacing…

Investing in capital equipment always involves an analysis of the return on investment (ROI), but never as much as during a recession. The question this year is often, "Our company is already tightening its belt, is this equipment going to help us save a lot of money in a relatively short time…

The conventional wisdom is that the United States no longer produces much. The notion that globalization has dealt a fatal blow to the U.S. manufacturing sector is a widespread one. It has become common to hear people declare that "everything is made in China!" Not only do most believe the United…

It is widely known among quality and process improvement practitioners that the lack of a clearly defined scope or charter is perhaps the leading cause for projects not getting started or completed on time and within budget. What are other causes? From my experience, the No. 2 cause for restarting…

Analytic statistical methods are in very strong contrast with what is normally taught in most statistics textbooks, which describe the problem as one of “accepting” or “rejecting” hypotheses. In the real world of quality improvement, we must look for…

Long before Six Sigma; long before SPC; long before ISO, TQM, TQC, ZD, and Mil-Q-9858A there were quality products. Quality meaning both goodness and defect-free. Look at furniture made around the time of the America Revolution. It was excellent. Fine inlay, precision joints, superior finishing.…

In “The Power of Observation—Part 1,” we learned that a good portion of problem solving should be devoted to a thorough understanding of what’s going on before any corrective action steps are taken.
In many cases, too much time is spent on proposing various solutions before the problem has been…
The New Yorker magazine featured a cartoon showing a discussion between a salesman and his sales manager. The despondent salesman asked, “I know you’re always telling us to sell the sizzle and not the steak, Mr. Bollinger, but just what is the sizzle of a 90º elbow, flexible-copper fitting?”…

You have a carefully crafted clay prototype made by a top design artist. Each detail is exquisite and you want to make sure every last one is molded into the finished article. Contact measurement isn't an option, because the piece is too complex and too malleable for touch probes. You need…

It can be extremely difficult if not impossible to have an antiquated, document or paper-based quality management system (QMS) work for a company. To possess, build, and support this type of management system burdens the organization.
On the other hand, a QMS that is electronic, linked, or…

Some authors recommend that you have to wait until you have the range chart “in control” before you can compute the limits for the average chart or the X chart. Why this is not true will be the subject of this column.
To illustrate the issues we will once again use the NB10 data. The 100 values are…

One of the earliest quotes I remember from a general manager: “If my manufacturing manager and quality manager weren’t at each other’s throats, then I would be concerned.” At the time, as a young graduate mechanical engineer acting a quality control manager for a small aerospace firm, I thought…

I often get assignments at organizations where I am required to take aside a group of people, either within the building facility or off campus, to focus on issues or problems. Typically these groups spend a considerable amount of time to summarize and present a well-defined problem. The next step…

Besides the fact that it flies, an airship—better known as a blimp—has about as much in common with other aircraft as a whale has with fellow sea creatures.
Among a blimp’s unique design elements are custom fan blades used to cool its engine. The fan blades were especially problematic for…
