Advanced GD&T has found its greatest application in mass production, where interchangeability of blindly selected parts is essential. Without GD&T and tolerance analysis, there is no way to know what parts have been designed such that all manufactured parts will fit together at assembly. This is becoming more critical today due to ever more powerful design tools and more restrictive business practices.
Participants will be trained to apply tolerance stack-up analysis techniques to a wide variety of assemblies per GD&T requirements.
Demonstrate a thorough understanding of GD&T Fundamentals and Tolerance Stackup.

Benefits of Attending
Geometric Dimensioning and Tolerancing (GD&T) and the tolerance stack-up Analysis eliminates the trial and error approach to product design. It should be viewed as a design methodology ensuring dimensions and tolerances are developed to suit feature function and mating relationships. Thus by leaning Advanced GD&T, one could be benefitted:
- It helps in eliminating guessing at product tolerancing, resulting in fewer prototype iterations and drawing revisions.
- It specifies the maximum available tolerance for manufacturing while protecting feature function.
- It provides clear instructions for quality control by using established rules governing part setup and tolerance zone interpretation, ensuring repeatable measurement results.
- It helps in controlling machine allowances, wall thickness and interface dimensions on castings and fabrications.
- It helps in developing multiple sources of supply by providing a complete product definition with a single dimensional interpretation.

Feedback From Past Participants
“This training program has helped to take complete knowledge on manufacturing variations on the design”
“ Now we can design the products better from what we have learned from the training session”
“Advanced GD&T should be introduced in all manufacturing companies for better dimensioning and understanding”
