Geometric Dimensioning and Tolerancing

Why should you attend?

Geometric Dimensioning and Tolerancing (GD&T) is a critical aspect of modern engineering design, providing a comprehensive framework for defining the geometry of parts and assemblies. This course begins by exploring the limitations of traditional coordinate tolerancing methods and highlights the advantages that GD&T offers over conventional dimensioning techniques. Through hands-on exercises, participants will gain practical experience in analyzing engineering drawings using both methods, fostering a deeper understanding of GD&T's superiority. The course delves into the latest GD&T standards and symbols, ensuring that learners are well-versed in the most recent revisions and governing bodies. Participants will engage in exercises to identify and interpret these symbols on provided drawings, solidifying their comprehension. Fundamental concepts such as basic, critical, and reference dimensions are covered extensively, along with feature control frame usage and the virtual condition concept. As the course progresses, learners explore form controls like flatness, straightness, circularity, and cylindricity. They will understand their implications on design and production through practical measurement exercises. The significance of Rule #1 and Rule #2 is explained alongside bonus tolerance applications and worst-case boundary analysis. Further topics include datums and datum reference frames, orientation and profile controls, location and runout controls, composite tolerancing techniques, modifiers' effects on tolerance zones, and surface quality considerations. Practical activities based on real-world case studies ensure that participants can apply GD&T principles effectively in various production scenarios.
