Tolerance Stack-Up Public Seminar - Register Today!

Cost: $795* per person and includes continental breakfast, course materials, hot lunches, breaks, and a pocket guide.

Course Description: (2 days) This advanced training teaches you how to study the cumulative effect of part tolerances in order to reduce product costs. You'll learn how to establish part tolerances, perform 2-D analyses of designs, use geometric tolerances in stack ups, and much more. Numerous assemblies will be studied. A workshop to apply tolerance stack-up analysis techniques to student supplied problems may be included.

No seminars currently scheduled.

Who should attend: Designers and Design Engineers and those trouble shooting production problems who have already taken a fundamentals course in geometric dimensioning and tolerancing in accordance with the ASME Y14.5 Standard. Additionally, a GD&T Applications course is recommended.

The Need: Designers and Design Engineers must be able to determine how robust a design is at the sketch phase. Fit of parts is relatively easy to predict. Shift of parts within an assembly requires an understanding of advanced tolerancing concepts. This knowledge is required to perform manual 2-D and computer assisted 3-D analysis.

Course Outline:

  • Tolerance Allocation and Analysis
  • Why Do We Need to Do More Tolerance Analysis?
  • When should we do Tolerance Allocation/Analysis?
  • Responsibilities of those performing a tolerance analysis:
  • There are always design alternatives!
  • Within a Part
  • Exercises
  • Reality Check
  • Tolerance Stack-Up Analysis
  • Procedure Exercises
  • The Stack-Up Sizes of Internal and External Features
  • Datum Shift
  • Profile Tolerances
  • Exercises
  • Analysis with Multiple Parts
  • Exercises
  • Self Aligning Features
  • Runout
  • Tilt and Shift

  • "I've learned more in just a few hours with the Tec-Ease GD&T Hierarchy Coach than in 12 weeks taking a similar on-line program. I look forward to the time I get to spend viewing the presentations and taking the interactive quizzes. Here at FOX the Tec-Ease GD&T Hierarchy Coach is rated "best in class".

  • "Thank you for all that you do. Your "Tips" are INVALUABLE -- I frequently refer to the archive for advice when I run across a sticky tolerancing puzzle."
    - Barbara P.
  • "I must say that I think you are the best GDT trainer/vendor of the many available. I have purchased your GDT charts, aids, and "The GDT Hierarchy" and found them to be clear and well illustrated."
    - Michael W.
  • "I absolutely love this course! (The GD&T Hierarchy Coach) I can go as slow as I want and go back and review slides if I need to. This is the way to go. I don't interrupt others learning, yet I get to fully understand before I move on."
    - Gwen M.
  • "Things are going well with our project. In less than a year we will be shipping a clinically significant, quality changing product to China from a US manufacturer. Cost competitive with great clinical outcome. I love the approach. I appreciate your help on this project. We have had a lot of feedback from our supply base saying great use of datum's and design for manufacturability."
