Tolerance Stack-Up (TSU)
2 days

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: 
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 2-D analyses of designs, use geometric tolerances in stack ups, and much more. Numerous assemblies will be studied. A workshop to apply tolerance stack-up analysis techniques to student supplied problems may be included.
 

Tolerance Allocation and Analysis Why Do We Need to Do More Tolerance Analysis? When should we do tolerance allocation/analysis? Responsibilities of those performing a tolerance analysis: There are always design alternatives!  Within a Part Exercises Reality Check Tolerance Stack-Up Analysis Procedure Exercises The Stack-Up Sizes of Internal and External Features Datum Shift Profile Tolerances Exercises Analysis with Multiple Parts Exercises BRING YOUR CALCULATOR!
