Tolerance Stack-up Fundamentals C0842

Analysis of tolerance stacks varies widely. This web seminar introduces the basic tools to create a common methodology for tolerance stack-ups, and ensure seamless documentation. Participants will create 1-D tolerance stacks for parts and assemblies that use geometric dimensioning and tolerancing using a tolerance stack spreadsheet. This simple, manual spreadsheet method produces an easily interpreted and checked documentation trail, and is easily adaptable to common electronic spreadsheet programs. Multiple examples will be provided to assist engineers in applying tolerance stack-up fundamentals to Y14.5 issues.

Learning Objectives
By connecting with this web seminar, you will be able to:
  • Perform and develop a tolerance stack-up analysis
  • Correctly enter geometric feature control frame data into a tolerance stack
  • Apply a common step-by-step methodology to tolerance stack analysis

Who Should Attend

Engineers familiar with concepts and practices contained within Y14.5 and who are looking for a fundamental step-by-step process for getting geometric dimensioning and tolerancing (G D & T) into a tolerance stack will benefit from this course. A basic understanding of G D & T symbols and concepts is required.


This course satisfies a requirement in the Product Engineering Tools and Methods Certificate Program.

  • Wrap-up
Registration Information
Registration for this live web seminar is available on a per-person basis, similar to purchasing a seat in a classroom. Participants attend an online session from work or home; anywhere with a PC with internet access and a telephone. The fee includes one connection to the conference calls (toll free telephone number provided for U.S. and select countries*) and assigned personal ID number; one connection to SAE's online training center (via WebEx); and access to a secure course in the SAE Learning Center that contains the presentations, supplemental materials, and assignments.

Registrations will be accepted until 5:00 p.m. the day before the start of the web seminar, but early registration is encouraged to allow for pre-course set-up and instructions.

*Global toll-free telephone numbers are provided for many countries outside the U.S., but are limited to those on the WebEx call-in toll-free number list. Check here to see if your country has a global call-in toll free telephone number for this web seminar. If your country is not listed, you may still connect using the US/Canada Call-in toll number or Voice over Internet Protocol (VoIP).

Although WebEx Training Manager will automatically launch when you join the web seminar, you or your system administrator are encouraged to download the plug-in in advance to help ensure successful setup. Click here, then follow the onscreen instructions.

Multiple Seat Discount - Does your company have a group of employees who need this course? Register one individual at the appropriate member or list price, then register additional employees at half off the list price. Registration by phone with SAE Customer Service is required to take advantage of these discounts.

If you cannot attend, you may register a substitute in your place or transfer your registration to a future offering. A full refund is issued if you notify SAE at least 14 days prior to web seminar start date. If canceled less than 14 days prior, the full fee is charged. For $50, you may process a one-time transfer to a future offering within one year of canceled web seminar. Canceling may reduce group discounts.
