Advanced GD&T Competencies: Composite Positioning Web Seminar RePlay PD331321ON

While the basics of position are covered in a standard Geometric Dimensioning & Tolerancing (GD&T) course, and sometimes a lone example of composite position is given, those discussions often overlook the variations allowed that enable more accurate control based on part function. This advanced web seminar will clarify the proper use of “double-decker” position controls in GD&T. There are two distinct types: composite position (one symbol) and two single-segment position controls (two symbols). These are commonly used to locate patterns of features (bolt circles, etc.), but they are rarely taught in any depth. In this course, 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.

Many samples will be shown of the proper tolerancing of patterns of holes and pins that use each method. Examples and exercises will be provided to allow participants to practice several calculations. Learning these advanced techniques will permit better communication of part and assembly requirements between designers and manufacturers.

Objectives

By participating in this course, you will be able to:

  • Explain composite positioning tolerancing
  • Explain two single-segment tolerancing
  • Apply the appropriate callout based on functional requirements
  • Describe gages for each and calculate gage sizes

Materials Provided

  • 90 days of online single-user access (from date of purchase) to the approximately one and one half hour recorded presentation
  • Course workbook (downloadable, .pdf's)
  • Online learning assessment
  • Instructor follow up to your content questions
  • .15 CEUs*/Certificate of Achievement (upon completion of all course content and a score of 70% or higher on the learning assessment)

*SAE International is authorized by IACET to offer CEUs for this course.
