Tolerance Stack-up Fundamentals

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.

What Will You Learn

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

Is This Course For You

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.
