Course Description:

This three-day course is a continuation of Basic GD&T, again focusing on practical GD&T application, and introducing additional advanced concepts such as the Datum at Virtual Condition Rule, tolerance calculation and more complex GD&T controls.

This program is designed for anyone who is currently familiar and proficient with the concepts and practices of GD&T. Particular emphasis is placed on those who are responsible for specifying and interpreting technical documentation.

Course Length - 3 days

OBJECTIVES

• Review the basic concepts and introduce the more complex concepts of the Y14.5M standard.
• Provide participants with the knowledge of proper Datum Feature selection and specification
• Enable participants to properly interpret and apply each of the Y14.5M controls and rules
• Enable participants to calculate functional tolerances for position and other tolerances

PROGRAM OUTLINE

• The program begins with a review of GD&T, then continues with practical team exercises designed to enhance knowledge, build confidence, and nurture a team environment. This class is a minimum lecture, maximum experience and participation format. Topics include:
  
  - Introduction: objectives, review Basic GD&T.
  - General rules of dimensioning and drafting review.
  - Review of the more complex controls: composite position, projected tolerance   zone, etc.
  - Datum Reference Frames: proper selection and utilization exercises.
  - Calculating tolerances for maximum producibility and 100% interchangeability.
  - Functional gauge design: "Soft" or "Paper" as well as tooled gauges
