There is no more exciting measurement system gaining momentum today than CNC CMMs. More and more facilities are realizing how much time is saved by measuring a part while recording a PPG (part program) and then measuring the next 50-100 parts with the click of a mouse. The true phenomenon involved with these machines is not how fast they measure, but rather how precisely they can perform as compared to their predecessor, the manual CMM. This precision can be explained in 2 words-direction vectors.
Many of today's versions of CNC CMM software have the capability to
use a teaching mode where circles, planes, and cylinders can be measured in an auto-measure ...
