Course Description

This course covers instruction and practice of precision measurement with tools commonly used by the machinist to produce and measure part features. This course introduces the proper use, applications and parts of the outside, inside, and depth micrometers; the Vernier caliper; dial indicators; and the dial bore gage commonly used by the machinist to verify and manufacture part features to print specifications. In addition, the participants will learn how to use some of the basic operations of the Coordinate Measuring Machine (CMM) and Precision Comparator.


This course is designed for inspectors, quality assurance specialists, and machinists. This course offers a background inaccuracy requirements and interpretation of tolerances that ensures quality parts for customers.
