Tolerance Analysis with GD&T

Back to On-Site Training

Who should attend: Designers and Design Engineers and those trouble shooting production problems who have already taken a fundamentals course in geometric dimensioning and tolerancing in accordance with the ASME Y14.5 Standard. Additionally, a GD&T Applications course is recommended.

The Need: Designers and Design Engineers must be able to determine how robust a design is at the sketch phase. Fit of parts is relatively easy to predict. Shift of parts within an assembly requires an understanding of advanced tolerancing concepts. This knowledge is required to perform manual 2-D and computer assisted 3-D analysis.

 

 

Course Description: (16 Hours)

This advanced training teaches you how to study the cumulative effect of part tolerances in order to reduce product costs. You’ll learn how to establish part tolerances, perform 1D analyses of mechanical parts and assemblies, including all types of geometric tolerances. Numerous example exercises will be studied. A workshop to apply tolerance analysis techniques to student supplied problems may be included.
