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.
You are here:
Tolerance Stack Analysis
Participants will learn a methodical procedure for performing tolerance stacks on parts and assemblies. A simple spreadsheet format is used to account for variation such as ± tolerances, but much of the course will focus on geometric tolerances (GD&T), and how each symbol may or may not contribute to a stack. Many practice exercises are included throughout, to reinforce each concept as it is covered.

In-Person Training
In-Person Training consists of public classes conducted by one of our subject matter experts at one of our designated locations in one or more consecutive days.
Target Audience
Course Objectives
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.

Virtual Live Training
Our Virtual Live Training classes are conducted through an online platform by one of our subject matter experts in one or more sessions.
Target Audience
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 16-hour Tolerance Stacks program is designed for engineers and others who work with stacks.
