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.
By connecting with this course, you will be able to:
This advanced-level course is intended for designers, product engineers, manufacturing engineers, manufacturing personnel, and quality/gaging inspectors with a basic knowledge of GD&T concepts. It is a companion to the Advanced GD&T Competencies: Composite Positioning and Datum Usage web seminars.Prerequisites
