This course is targeted at
those who have already been trained in the basics of
Dimensioning and Tolerancing. Even the most advanced
practitioners will learn more than they ever thought possible.
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
● Advanced GD&T Concepts/Applications
● Tolerance Stack-Up Analysis
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.
step-by-step procedures for dimensioning and tolerancing
parts and assemblies.
It shows how to
analyze the tolerances applied using both worst case and
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.
