After learning the GD&T concepts, many participants find that they need a methodical way of adding these tolerances into an overall stack-up analysis. The 2-day Tolerance Stacks program is designed for engineers and others who work with stacks.
While there is no standard way to do stacks, a spreadsheet method is introduced which allows for both traditional plus/minus tolerances as well as geometric tolerances. We even teach how to handle the MMC "bonus" and "shift" tolerances, which are sometimes ignored, even in "worst-case" stacks.
