The purpose of this session is to clarify the proper use of the profile tolerances in GD&T (geometric dimensioning and tolerancing), and to show the full potential of these two symbols. A basic GD&T course covers the general meaning of profile, particularly with contoured surfaces, but many of the nuances are not covered. This session is intended for anyone who has basic knowledge of GD&T, whether involved in design, manufacturing, or quality. Since profile of a surface is arguably the most powerful GD&T symbol, its full potential will be explored: it can be used to control size, form, orientation, and location, and its relationship to datums can be varied. The many examples given in this session will also illustrate several of the new options for profile that were introduced in the ASME Y14.5-2009 standard.

During this session, participants will learn how to:
  • Explain when profile tolerances require a datum reference
  • Determine which aspects of GD&T a given profile tolerance controls
  • Interpret unilateral, bilateral, and nonuniform tolerances
  • Describe how to properly measure profile tolerances

Session Outline:
  • Review of profile of a surface and profile of a line
  • Using profile without datums
  • All around and all over
  • Locating a profile zone with toleranced dimensions
  • Using the MMB modifier with profile
  • Composite profile
  • The "U" modifier
  • Nonuniform tolerancing

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