Course Description
Identify 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.”
Participants are expected to purchase the following book for class:
“Dimensioning and Tolerancing Principles for Gages and Fixtures” ISBN: 9780791833483
