Advanced Concepts of GD&T 1994 3-day ET2011

This course teaches the advanced concepts of GD&T as prescribed in the ASME Y14.5M-1994 Standard. 

Utilizing the expertise of world-renowned GD&T expert Alex Krulikowski, this course offers an in-depth explanation of advanced GD&T topics like composite tolerancing, tolerance analysis, datum selection, non-rigid part dimensioning, and many more key dimensioning topics, including the system approach for part dimensioning. Newly acquired learning is reinforced throughout the class with more than 250 practice problems.

Each attendee receives a robust collection of learning resources including:
  • Advanced Concepts of GD&T (ASME Y14.5M-1994) textbook
  • GD&T Ultimate Pocket Guide 
  • Fundamentals of GD&T Exercise Workbook
  • 90-day access to Fundamentals of GD&T 1994 web training course
Thousands of students have learned GD&T through Alex Krulikowski"s textbooks, self-study courses, computer based training, and online learning center. Students who attend this course walk away with more than knowledge—they gain on-the-job skills because the learning materials are performance-based.

Learning Objectives
By attending this class, you will learn to:
  • Explain the importance of product design and functional dimensioning
  • Define the terms “feature” and “feature of size”
  • Recognize which dimensioning standards apply to an engineering drawing
  • Explain the fundamentals of drawing interpretation and how to handle substandard drawings
  • Recognize the difference between a rigid and a flexible (non-rigid) part
  • State the requirements for tolerancing parts measured in the restrained state
  • Identify the two special considerations for datum usage on restrained (non-rigid parts
  • Calculate advanced applications of form controls
  • Describe uses, advantages, misconceptions, and common errors of the datum system
  • List nine common datum feature types
  • Describe advanced datum target concepts
  • Explain how to specify / interpret specialized datum feature applications
  • Describe modifier usage in tolerance of position applications
  • Describe the effects of simultaneous and separate requirements with tolerance of position
  • Explain composite position tolerancing and multiple single-segment position tolerancing
  • Interpret tolerance of position applications with a conical tolerance zone
  • Explain composite profile tolerancing and multiple single-segment profile tolerancing
