Tolerance Stack-up Analysis

Date : 23 to 25 May 2022

Time : 1310 Hrs to 1730 Hrs

Introduction

Manufacturing process, productivity and cost are often determined by component tolerances. If components are incorrectly toleranced, it leads to assembly problems. Too tight a tolerance leads to higher cost. Designers are expected to tolerance components optimally.

Dimensional variations in production parts accumulate or stack up statistically and propagate through an assembly kinematically, causing critical features of the finished product to vary. Such variations can cause costly problems, requiring extensive rework or scrapped parts. One of the effective tools for managing variations is Tolerance Analysis. Tolerance Analysis is a quantitative tool for predicting the accumulation of variation in an assembly by performing a stack-up analysis, reduces manufacturing costs by improving producibility and also enables design engineers to determine, how robust a design is at the drawing phase.

Keeping this in view, Indian Machine Tool Manufacturers' Association (IMTMA) is organizing a 2 day online training on Tolerance Stack-up Analysis.

  • Case study and Stacks using multiple geometric controls
  • Tolerance Analysis and Tolerance  Allocation
  • Statistical Tolerance -Theory, Example and exercise

Key Take Aways



  • Compute Tolerance Stack-ups in parts and Assemblies
  • Determine if the assemblies/parts can work at their worst-case condition or maximum statistical variation
  • Modify/redistribute tolerances to satisfy function and manufacturability
  • Troubleshoot parts and assemblies which had field failure due to tolerance accumulation issues

Participant Profile

This programme will benefit designers / product design engineers responsible for specifying, interpreting and analyzing tolerances.

Pre-requisite: This programme will directly start with tolerance stacks. Hence, Knowledge of Engineering Drawing and GD&T principles will be a pre-requisite for participants to learn the techniques of tolerance stack-up analysis. 

There will be a pre-course questionnaire after registration.
