Advanced GD&T Competencies: Datum Usage Web Seminar RePlay
While the basics of datums are covered in a standard Geometric Dimensioning & Tolerancing (GD&T) course, those discussions often overlook the variations that enable datums to be used in complex ways. This advanced course will detail the proper use of datums, showing their full potential to make your drawings as effective as possible. 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 web seminar, 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. Learning these advanced techniques will allow designers to better communicate certain requirements.
What Will You Learn
By participating in this course, you'll be able to:
- Explain the difference between a datum and a datum feature
- Select appropriate datums for irregularly shaped parts such as body or interior panels
- Properly simulate given datums
- Explain effects of a modified datum on a geometric tolerance
- Interpret new datum tools such as translation and custom degrees of freedom
