Providing you have an understanding of GD&T fundamentals, this course teaches the thought processes involved in assigning GD&T to components. It will change the way many engineers think about part tolerancing.

Utilizing the expertise of world-renowned GD&T expert Alex Krulikowski, the course focuses on what constitutes good and poor drawing practices, common dimensioning methods used in industry, using GD&T to communicate system functions on component dimensions, and the logic of how to apply GD&T to components.

Newly acquired learning is reinforced when students perform a design function analysis on a part assembly provided by your company, then specify GD&T on assembly components during the workshop. (This is optional in case of concerns over drawings and privacy.)

  • What You Receive
  • Learning Objectives
  • Who Should Attend
  • Topical Outline

Each attendee receives a robust collection of learning resources including:

  • A copy of Applications of GD&T Workshop Exercise Workbook, by Alex Krulikowski
  • Course notes
  • Drawing handouts
  • Official certificate of completion

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 courses like this one walk away with more than knowledge. They gain on-the-job skills because the learning materials are performance-based.

By attending this class, you will learn how to do a design functional analysis on an assembly and use this information to assign dimensions and tolerances. They will also learn how to select datum features and how to fully define component surfaces using GD&T. Establishing tolerance values is not covered. Small groups (8-12) are most effective in this workshop. The students will work in teams and actually create GD&T tolerance mark-ups of their company parts in the workshop.

By attending this class, you will be able to:

  • Describe the importance of technically correct drawings
  • List three major areas that affect the creation and interpretation of technically correct drawings
  • Explain the common approaches to part tolerancing
  • Identify and specify datum features based on the fit and functional requirements of the part
  • Use GD&T to communicate functional requirements of a component
  • Describe how to specify nonfunctional dimensions
  • Explain the five-step approach to functionally dimensioning a component
  • Apply the five-step method to functionally dimensioning a component to your company product

Who Should Attend
This course is designed for product engineers, designers, checkers, and engineering managers, and supplier quality engineers.

Prerequisites
Please be aware that this is not an introductory course. In order to understand the course content, students should have complete 16 hours of formalized classroom training in GD&T or ETI’s Fundamentals of GD&T course. You should also have experience interpreting or applying GD&T in an industrial setting and working knowledge of the ASME Y14.5-2009 Standard.
