Chapter 5:
Measuring
Measurements can be conducted using video edge detection on manually controlled systems, or on auto-
mated CNC systems. Features can be probed manually by the user, or automatically under program control.
The measurement of features can be limited to probing points, or might require the construction or creation
of new features in addition to probing. However measurements are conducted, the fundamental measure-
ment process and the tools required to perform measurements remain unchanged. Here’s what you’ll find
