Basics of Tolerance Stack-up Analysis and Fits with GD&T

Basics of Tolerance Stack-up Analysis and Fits with GD&T

Understanding Tolerances and tolerancing schemes is a very important part of Mechanical design .

In most cases Tolerances are directly detrimental to the functional performance of a mechanical product.

This course attempts to cover the key concepts in tolerance stackup , limits, fits and statistical tolerancing with examples .

Tolerance stackup analyses are critical in applications where small changes in dimension of parts can have heavy consequences.

What we will cover in the course?

• What is tolerance? What are sources of variation ?

• What are Fits , the nomenclature, types and Tolerance zones

• How to decode and interpret a Fit specification and convert it into limits

• How to Define a specification of a Fit for a specific application

• How to do a simple tolerance stackup ? Generic procedure and factors to be considered?

• How to develop Loop Diagrams in Stackup ?

• Assembly shift in Tolerance analysis

• How is assembly shift calculated

• Stackup with GD&T

  • How to find Boundary conditions accounting for size and positional variations

  • How to derive the individual specifications in tolerance table

  • How to develop the envelopes for GD&T controls

• Statistical Tolerancing

  • Why Statistical techniques are used?

  • What is normal distribution

  • What is difference between worst case and statistical analysis

  • What is Process capability index

The course is structured to provide learning  in a methodical step by step way with clear explanations .

Core Learning outcome is to provide a strong foundation concept in Tolerance analyses for mechanical Engineers in design and manufacturing.
