17.1. TOLERANCE STACK-UP
When multiple parts are "stacked" and have cumulative tolerance buildup, the traditional way to handle the stack-up variation is to assume "worst case" on each component. (Allow for all parts being at the high end of the tolerance or all parts being at the low end of the tolerance.) "Stacked" parts are akin to having multiple blocks, placed one block on top of another.
NOTE
Tolerance Stack-Up Analysis
This is the process of evaluating the effect that dimensions of all components can have on an assembly. There are various methods used, including worst case, RSS (root sum-of-squares), modified RSS, and Monte Carlo simulations.
17.1.1. Example, Part A
Assume there is a stack of 10 parts, each a nominal 1.000" thick, and ...
