Advanced GD&T Competencies: Profile of a Surface Web Seminar RePlay

Tato část není lokalizována

While the topic of profile is covered in a basic Geometric Dimensioning & Tolerancing (GD&T) course, those discussions often ignore the variations allowed with these symbols that enable them to be used in complex ways. This advanced web seminar will clarify the proper use of the profile tolerances in GD&T and uncover the nuances of these two symbols. 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. Learning these advanced techniques will allow designers to better communicate certain requirements. The 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.

Objectives

By participating in this course, you\’ll be able 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
