Tolerance Stacks: Advanced Tolerance Stacks
The purpose of this session is to give participants more practice in performing tolerance stacks that involve GD&T (geometric dimensioning and tolerancing), as well as an understanding of how statistical methods can impact a stack. A basic knowledge of geometric tolerancing is required, and familiarity with the basic stack spreadsheet method is recommended. The session begins by reviewing the unique factors known as "bonus tolerance" and "shift tolerance" (the "M" symbols), which are often erroneously ignored in tolerance stack-up analysis. Multiple examples will be provided to show specific applications, and practice exercises for the participants are included. Then the focus turns to the world of statistical stacks, which can often give more realistic results than a purely worst-case calculation. Participants will learn how to implement the root-sum-square (RSS) formula, as well as a modified RSS approach, along with a discussion of the caveats to consider when using these methods.
At the end of this session, participants will be able to:
