Advanced GD&T: Composite Position
This session clarifies the proper use of "double-decker" position controls in GD&T (geometric dimensioning and tolerancing). There are two distinct types: composition position (one symbol), and two single-segment position controls (two symbols). These are commonly used to locate patterns of features, but they are rarely covered in a Fundamental GD&T training course. In this session, participants will learn the difference in showing one vs. two position symbols, and the importance of the datum references in understanding each meaning, per the ASME Y14.5-2009 standard. The target audience is design engineers, manufacturing engineers, and inspection personnel who are familiar with the basics of GD&T. Many samples will be shown of the proper design and inspection of patterns of holes and pins that use each method. Examples and exercises will be provided to allow participants to practice several calculations.
During this session, participants will learn how to:
