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.

Topical Outline

  • Introduction and review
    • Introduction and tolerancing review
    • Tolerancing strategies
    • Review of G D & T

Session 2
  • Stack fundamentals
    • How to identify the stack path
    • The two-column stack spreadsheet
    • Entering dimensions into the spreadsheet
    • Examples with coordinate dimensions

Session 3
  • Factoring G D & T into a Stack
    • Location and runout tolerances
    • Profile tolerances
    • Form and orientation tolerances

Session 4
  • Bonus and shift tolerance in a stack
    • Overview of bonus and shift tolerance
    • Part vs. assembly stacks
  • Wrap-up

John Paul BelangerJohn-Paul Belanger is president of Geometric Learning Systems, a consulting firm specializing in geometric dimensioning and tolerancing (G D & T). For over ten years, he has trained people throughout North America and Europe in the proper interpretation and application of G D & T per the Y14.5 standard by using practical examples. Mr. Belanger is certified by the American Society of Mechanical Engineers as a Senior G D & T Professional, and has worked with a wide range of companies in the automotive, aerospace, electronic, and other industries to apply tolerances and perform stack calculations. He holds a B.S. in aerospace engineering from the University of Michigan specializing in aircraft design and safety.

Registration Information
Registration for this 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 (at least 56K) and a telephone or VoIP headset. The fee includes one connection to the two hour conference call (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, session recordings, 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.

NOTE: The course presentation will be recorded and made available for 30 days to those who register by the deadline.

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 this discount. Register all individuals at the same time or mention the confirmation number for the first registrant. The offer is good for only the same web seminar offering. All registrants will receive a personal account and opportunity for CEUs.

Can't attend on the date/time above? The presentation will be recorded and made available for 30 days to those who are registered, regardless of availability for the live session. If you still need to cancel, transfer to a future offering, or designate a substitute, a full refund is issued if you notify SAE at least 14 days prior to the web seminar start date. If less than 14 days prior, please contact SAE Customer Service to discuss options*. NOTE: SAE reserves the right to cancel web seminar and cannot be held responsible for related costs incurred by registrants other than the registration fee.

*Cancellation penalties may apply.
