12-Introduction to Geometric Dimensioning and Tolerancing (GD&T) (One Half Day, In-person)
Dr. Jaime Berez (University of North Carolina – Charlotte)
Tuesday, November 5, 2024 (8:00 AM – 12:00 Noon)
Tutorial Description
This tutorial will cover the fundamentals of geometric dimensioning and tolerancing (GD&T) with additional focus on engineering product specification best practices, relevance of GD&T in the age of digital manufacturing, and validation/inspection. GD&T, synonymously known as geometric product specification (GPS), offers a set of tools for design engineers to communicate geometric specifications to manufacturers and inspectors via engineering drawings. While GD&T is well-known in industry, it is not commonly taught in engineering classrooms and often suffers from misconceptions even among practicing engineers. Thus, a review of the fundamentals is often advisable especially when considering complex product definition problems. GD&T as per ASME Y14.5-2018 will be emphasized, but ISO TC 230 standards will also be briefly discussed.
