Hotel & Travel Information

This course is designed to help product design personnel create tolerance stacks for parts and assemblies that use Geometric Dimensioning & Tolerancing. Those who will benefit most are designers and engineers who are responsible for creating the GD&T callouts for engineering drawings and product models, and who want to be more confident in how the assigned geometric tolerances interact and stack up. The course begins with a quick review of Y14.5 concepts, and then introduces the benefits and uses of a tolerance stack spreadsheet. Participants then learn detailed procedures for performing tolerance stacks on parts and assemblies, beginning with coordinate tolerances and moving on to geometric tolerances.

The course will eliminate confusion over how to include the bonus and shift in a tolerance stack: for example, when using tolerance of position with the MMC modifier. The simple, manual spreadsheet method used throughout the course produces a straightforward documentation trail that is easily interpreted, and readily adaptable to any company's electronic spreadsheet program. Results can be quickly and easily checked, and revisions can be made with ease. Students receive extensive practice at creating stacks, and should bring a calculator or laptop computer equipped with MS Excel for the numerous student exercises.

Each attendee will receive a copy of the "Tolerance Stack Analysis Using GD&T" textbook and an Excel template for generating stacks.

Note: A similar course is available live online or on demand.

Learning Objectives
By attending this seminar, you will be able to:

  • Correctly calculate and apply bonus, shift, virtual condition, and resultant condition
  • Perform and develop a tolerance stack-up analysis
  • Correctly enter geometric feature control frame data into a tolerance stack

Who Should Attend
This course is intended for designers and engineers who are currently generally familiar with the principles, concepts and practices contained within Y14.5, and who are looking for a comprehensive step-by-step process for getting GD&T into a tolerance stack.

Prerequisites
Previous experience with Geometric Dimensioning & Tolerancing principles, concepts, and practices is required.
