Probes

Chapter 4:

Probes

Measurements are conducted using video edge detection on manually controlled systems or on automated

CNC systems. Part features can be probed manually by the user or automatically under program control.

This chapter explains how to use and calibrate video probes.

NOTE

The measurement, construction and creation of features using video probes is ex-

plained in Chapter 5: Measuring
