"Advanced Geometric Dimensioning & Tolerancing"

Covers Advanced GD&T and related topics!

Who Should Attend?

This course is targeted at those who have already been trained in the basics of Geometric Dimensioning and Tolerancing.  Even the most advanced practitioners will learn more than they ever thought possible.

 

Course Content: 
Based on the comprehensive GD&T textbook co-published by the American Society of Mechanical Engineers (ASME) Geometric Dimensioning and Tolerancing-Applications, Analysis & Measurement [per ASME Y14.5-2009], this course has the ability to cover almost every facet of tolerancing.  Some of the general topic categories available to be covered are listed below. 

       ● GD&T
       ● Advanced GD&T Concepts/Applications

       ● Tolerance Stack-Up Analysis
       ● Statistical Tolerancing                     
       ●
Measurement, Inspection and Collected Variables Data Analysis
       ● Functional Gage and Fixture Design, Dimensioning and Tolerancing

      ●New Rules, Symbols and Concepts in Y14.5-2009 and the differences between ASME Y14.5M-1994 and Y14.5-2009

 

Course participants can choose which specific topics from the

text will be emphasized and discuss how these concepts can be applied

directly to their company’s products.        

 

Based on the rules found in the ASME Y14.5 standard, this course also covers topics from other recently published standards by ASME not found in older texts.

  • It includes step-by-step procedures for dimensioning and tolerancing parts and assemblies.

  • It shows how to analyze the tolerances applied using both worst case and statistical analysis.

  • It demonstrates the connection found between the application of functional geometric tolerances and its effect on manufacturability and inspection, stressing optimal ways to achieve a high-quality product at the lowest possible cost to the consumer.
