Dimensioning and Tolerancing Principles for Gages and Fixtures

Learn the rules, principles and practices of gage and fixture design, dimensioning and tolerancing per the newly approved standard, “Y14.43-2011 — Revision of ASME Y14.43-2003 (R2008) — Dimensioning and Tolerancing Principles for Gages and Fixtures.”

This course can be applied to the Dimensioning and Tolerancing Certificate.

Benefits and Learning Outcomes

  • Learn gage and fixture design, dimensioning and tolerancing per the approved Y14.43-2011 standard
