Tolerance Stacks Training Course Outline

Allocating tolerances that meet assembly build, performance, process capability and least-cost requirements have always been a challenge for the manufacturing industry.  G D & T incorporation in any Company is never complete without the Understanding and Implementation of Tolerance Stacks as a part of the design process.
Effect of part tolerances on assembly build and performance, least-cost tolerancing of part dimensions influencing assembly build and performance are an intrinsic part of the Tolerance Stack Up Analysis Course offered by EGS India.
Who ShouldAttend:
Practising G D & T Engineers, Designers, Technicians and Dimensional Management team members having knowledge of G D & T.
Tolerance Stack Up Analysis

This course is about tolerancing methods to meet Fit, Form and Functional requirements in design. It teaches you how to perform Tolerance Stack Up Studies in Single and Multi-Dimensional requirements.

The course covers the following topics:

  • G D & T - Overview
  • Concept of Feature Control Frame and Bonus Tolerances
  • Defining Assembly/ Performance Requirements
  • 1D Loop Analysis
  • Conversion of Tolerances to Equi- Bi-lateral Tolerancing
  • Understanding Process Capability
  • Tolerance Analysis Methods - Worst Case, RSS, Modified RSS, Process Centring RSS
  • Considerations in Design for Six Sigma
