16 – Introduction to Geometric Dimensioning and Tolerancing (GD&T)

Dr. Jaime Berez (University of North Carolina at Charlotte)

Tuesday, November 14, 2023
2:00 PM – 6:00 PM (EST USA)

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.

Dr. Jaime Berez is an Assistant Professor in the Mechanical Engineering and Engineering Science department at UNC Charlotte where he works with the Center for Precision Metrology, an industry-university collaborative research center. Jaime conducts research at the intersection of advanced manufacturing and metrology, often with a focus on metrology as applied to metal additive manufacturing (AM) machines and workpieces. His research often leverages geometric dimensioning and tolerancing (GD&T) and he is he is passionate about integrating engineering product definition concepts (GD&T, metrology, standards) into engineering curricula using strong teaching pedagogy. Jaime received his Ph.D. in mechanical engineering from Georgia Tech in 2023 and has previously done stints in the automotive and aerospace industries.
