Geometric Dimensioning and Tolerancing (GD&T) Fundamentals

To better define a product to a customer or supplier, Geometric Dimensioning and Tolerancing (GD&T) is often used as a symbolic way of showing specific tolerances on drawings. GD&T is a valuable tool that effectively communicates the design intent to manufacturing and inspection. It is governed by the technical standard ASME Y14.5-2018, published by the American Society of Mechanical Engineers.

 

This three-day course covers all aspects of GD&T. In additional to presenting the theory, multiple examples will be provided to show specific applications. Participants are welcome to bring sample prints to the class for discussion or private consultation.

Understanding what your customers are telling you in relation to surface finish and tolerances is commonly referred to as G,D&T.

"Geometric Dimensioning and Tolerancing (GD&T) is a system for defining and communicating engineering tolerances. It uses a symbolic language on engineering drawings and computer-generated three-dimensional solid models that explicitly describes nominal geometry and its allowable variation."
