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.

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.

Many industries, including the automotive and aerospace industries, must precisely measure the three-dimensional features of large objects. An increasingly popular way to do this is with the laser tracker, a device first introduced in the late 1980s.

The most important element in producing a quality product or service is the attitude of the people doing the work—not only the worker—but the attitude of all levels of management.

Laser line scanning is ideal for non-contact measurement applications - including inspection, cloud- to-CAD comparison, rapid prototyping, reverse engineering, and 3-D modeling. Laser line probes use a triangulation process to find the position of objects in space.

(Mahr Federal: Providence, Rhode Island) --­ Tapers play an important role in orthopaedic devices. Most hip and knee implants use tapers because they provide good alignment and can be "locked" into position.
