Advanced GD&T Webinar Series: Part 1: Advanced GD&T: Datums
The purpose of this session is to take participants to the next level in using datums properly within GD&T (geometric dimensioning and tolerancing). Most people who use GD&T are familiar with traditional datums derived from flat surfaces, and have adequate knowledge of the principle of establishing 3-2-1 contact points. In this session, participants will learn to select, identify, simulate, and describe datums and datum features for special uses such as irregular shapes, flexible parts, and datum references that use the maximum material modifier. Also covered are several new modifiers and options given in the ASME Y14.5-2009 standard. The course is intended for designers, product engineers, manufacturing engineers, manufacturing personnel, and quality/gaging inspectors who have some experience with GD&T fundamentals.

During this session, participants will learn how to:
  • Explain the difference between a datum and a datum feature
  • Select appropriate datums for irregularly shaped parts
  • Properly simulate given datums 
  • Explain effects of the datum on a geometric tolerance
  • Interpret new datum tools such as translation and custom degrees of freedom

Session Outline:
  • Brief review of traditional datum usage
  • Selecting datums: surface vs. feature of size
  • Use of the MMB modifier (formerly MMC)
  • Using a pattern as a single datum
  • The new translation modifier
  • Applying the "M" modifier to a surface
  • Customized degrees of freedom
  • Irregular feature of size datums
  • Moveable datum targets

Who Should Attend:
  • Manufacturing engineers
  • Product engineers
  • Manufacturing personnel
  • Quality/gaging inspectors

Each session includes an approximately 70-minute presentation and a brief Q&A session at the end. Unlimited participants are allowed at each login site. All registrants receive 180 days of free access to the recording of the live session.
