Hotel & Travel Information

This two-day interactive course, based on the ASME Y14.5-2009 standard, provides an in-depth explanation of how to use tolerance stacks to analyze product designs and how to use geometric tolerances in stacks. You will learn the essential methods and concepts used for creating 1D part and assembly tolerance stacks. The course was developed utilizing the expertise of world-renowned GD&T expert Alex Krulikowski and features numerous practice problems and in-depth coverage of tolerance stacks applications.

Each attendee receives a robust collection of learning resources including:
  • A copy of Critical Concepts of Tolerance Stacks workbook
  • A Tolerance Stacks Drawing Package
  • An Excel tolerance stack spreadsheet template
  • A Tolerance Stacks Summary Chart
  • A copy of The Ultimate GD&T Pocket Guide ASME Y14.5-2009

Learning Objectives
By attending this seminar, you will be able to:

  • Describe how virtual condition affects the assembly of parts
  • Explain the importance of tolerance stacks and be familiar with stack methods, the stack form and the stack spreadsheet
  • Calculate part stacks using coordinate dimensions, runout and concentricity, profile tolerances, multiple geometric tolerances, position tolerances at RFS and MMC/MMB
  • Calculate assembly stacks using coordinate dimensions, runout and concentricity, bilateral and unilateral profile tolerances, multiple geometric tolerances, position tolerances at MMC/MMB
  • Calculate stacks using form and orientation applied to features and features of size

Who Should Attend
This course is valuable for individuals who create or interpret engineering drawings; product and gage designers; process, product, and manufacturing engineers; supplier quality engineers/professionals; CMM operators; and checkers.

Prerequisites
In order to understand the course content, students should have a good understanding of GD&T based on the ASME Y14.5-2009 Standard either through work experience or knowledge gained by participating in a course such as the ETI Fundamentals of GD&T 3-Day Workshop. Basic GD&T concepts will not be covered in this course.
