Inspecting Geometric Tolerances

Back to On-Site Training

Who should attend:

Product Engineers, Design Engineers, Quality Engineers, Tool Engineers/Designers' and Inspection Personnel. Prior knowledge of GD&T techniques (ASME Y14.5) will be helpful.

Course Description: (16 Hours)

This course will help give guidelines for selecting the most appropriate inspection method for a part feature. Participants will gain an understanding of design principles to produce low cost, functional gages. They will also be taught a method of practical datum selection as well as guidelines for using modifiers. Criteria for selecting company/division gaging policies and an overview of gaging equipment capabilities will also be covered.
