GD&T to ASME Y14.5 – Fundamentals

An intensive three-day course introducing the fundamental principles of GD&T (Geometrical Dimensioning & Tolerancing) to the ASME Y14.5 standard.

Course Description:

The course focuses on building a clear understanding of how the ASME Y14.5 standard works, how to interpret the symbolic language of the standards, and how to apply the rules consistently on engineering drawings.

The course incorporates client-supplied drawings in some of the practical exercises to reinforce key concepts and ensure relevance to participants’ own products.

Course Objectives:

By completing this course, participants will:

• Build a strong foundation - grasp the core principles that make the standards easier to understand

• Master the essentials - become fluent in the key terminology, rules, and most commonly used symbols from the standards.

• Apply with purpose - learn when and how to use tolerance symbols effectively, and how the standards are used, interpreted and applied across a part’s life cycle.

• Design for function - see how correct datum and tolerancing strategy enables a requirements-driven approach, ensuring fitness for purpose and unambiguous capture of design intent.

• Bridge textbook theory with practical application - Learn how tolerancing strategy is shaped by manufacturing and inspection realities.

• Gain practical confidence - work on practical exercises with real drawings and parts from GD&T Academy or client supplied, to gain hands on practical experience and ensure relevance to participants’ own products.

Who it is for:

This is our general course, designed to be accessible to participants from all industries — whether new to geometrical tolerancing or with prior experience.

The course is particularly valuable for:

• Design and Mechanical Engineers

• Inspectors and Inspection Planners

• Drafters

• Managers, Supervisors, and Production Associates

• Anyone who needs to read, interpret, or work with the standards on engineering specification

  
  

Requirements:

• Participants should have some familiarity with engineering drawings and a background in design, production, or inspection, including the ability to interpret how parts are represented on drawings.

• Delegates don't need to bring materials, laptops etc. All materials are provided by GD&T Academy.

• Participants are welcome to supply drawings or components, which may be integrated into exercises to enhance course applicability.

• An upper limit of 10 delegates is advised to ensure effective learning.
