Fundamentals and Applications of Geometric Dimensioning & Tolerancing (GD&T) Training

Days: 3

7:30 AM- 4:30 PM MST

Overview

Geometric Dimensioning and Tolerancing (GD&T) is a powerful tool for improving communication, design clarity, and manufacturing efficiency. This three-day course provides a comprehensive, intermediate-level introduction to the ASME Y14.5 standard, giving participants the knowledge and practical skills needed to interpret, apply, and communicate GD&T effectively across design, manufacturing, and inspection processes.

The course begins with the history and principles of Geometric Dimensioning and Tolerancing, demonstrating how it enhances design intent, ensures consistency across drawings, and facilitates collaboration between engineering, purchasing, and manufacturing teams. Participants will then explore frequently used geometric controls and tolerancing practices, with a focus on positions, datum reference frames, and feature control frames. Hands-on exercises reinforce real-world applications, helping attendees understand the advantages of GD&T in mechanical engineering and manufacturing workflows.

By the end of the course, attendees will be able to read and apply Geometric Dimensioning and Tolerancing standards with confidence, make informed decisions when selecting tolerances, and improve part functionality, quality, and communication throughout the product lifecycle.

Prerequisites

Participants need to have a working understanding of technical drawings (perspectives, sections, details, etc) in order to be fully successful in this Geometric Dimensioning and Tolerancing training.

Participants also need the ASME Y14.5-2018 Dimensioning and Tolerancing standard. This will not be supplied by Axeon.
