Geometric Dimensioning & Tolerancing - Virtual


This course is a virtual presentation of the two-day fundamentals course in GD&T.

Six two hour session of instruction plus three two hour sessions of Q&A.
Instruction will take place from 9:00am - 11:00am, break 1:00pm - 3:00pm.
Q&A will take place from 9:00am - 11:00am.

Industry uses GD&T to specify contractual requirements. Unfortunately, many people within industry have a flawed or incomplete understanding of the subject. Our basic course builds competence to correctly apply and interpret the rules, definitions, principles, and symbols per the American National Standard, ASME Y14.5 - 2018. This course provides a common language to improve communication, so set-up requirements and tolerance zones are clearly understood by all.

Session 1
  • Introduction to the course, timing, logistics, and expectations
  • Major changes in the standard: ASME Y14.5 - 2018
  • Features, features of size, and features without size
  • 12 geometric characteristics symbols
  • Datum features and datum schemes
  • Basic dimensions defining the perfect part
  • Feature control frames define tolerance zones
  • MMC, LMC, or RFS and bonus tolerance
  • MMB, LMB, or RMB and allowable datum shift
  • Course goals and objectives

Session 2

  • Four things GD&T controls
  • Presentation of tolerances in ASME Y14.5 - 2018
  • Rule #1, Independency and Continuous Features
  • Testing for compliance to Rule #1
  • Rule #2 for MMC, LMC, RFS and MMB, LMB, RMB
  • Virtual condition and resultant condition
  • Concepts used in the design of functional gages
  • Lesser known symbols and applications
  • Use of the diameter symbol in feature control fames

Q & A from Session 1 & 2
