This Advanced GD&T class is for those with some previous exposure to geometric dimensioning and tolerancing.  The morning begins with a review of the GD&T symbols and rules. Then some more advanced topics are covered, including an update about the revised Y14.5-2018 standard.  Also discussed will be the proper application of tolerances for designers, including a short module using a tolerance stack spreadsheet.

Learning Objectives

After participating in this course, participants will be able to:

    • Explain the less-common GD&T tools: translation, datum shift, resultant condition, all over boundary
    • Determine which datum features to choose based on function
    • Select proper GD&T symbols for a mock design
    • Perform tolerance stack calculations for both worst-case and RSS

Prerequisites: Participants should have some basic knowledge of GD&T.

Course Outline 

Part 1:  GD&T Review

    • Importance of engineering drawings
    • Benefits of GD&T
    • The need for geometric dimensioning and tolerancing

    • Review of GD&T rules and symbols

Part 2: Advanced Concepts

    • Resultant condition
    • GD&T with rigid vs. non-rigid parts
    • The dimensional management process
    • Datums at virtual condition (the MMB modifier)
    • Using GD&T with screw threads, gears, and splines
    • How to apply GD&T to a new design
    • How to choose MMC, RFS, or LMC
    • Simultaneous vs. separate requirements
    • Zero tolerance at MMC
    • Common GD&T mistakes
    • Boundary concept
    • All-around vs. all-over profile tolerance
    • Manufacturing and gauging concerns
    • Tolerance stack analysis using the “loop” method
    • Sample print review and wrap-up

Who Should Attend:  Process Engineers, Product Engineers, Quality Engineers, Quality Technicians and Quality Managers.

Cost: $375.00/person | $325.00/person if 3 or more persons
