GD&T (ASME Y14.5) in Practice - Fundamentals

Practical training in geometrical tolerancing to the ASME Y14.5 standard.

Course Description:

This intensive programme introduces the fundamental principles of geometrical tolerancing, with practical examples drawn from multiple industry sectors. The course provides a broad foundation that applies across all industries, and is delivered to the ASME Y14.5 standards.

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 with real drawings and parts from Aerospace, Medical Devices, Automotive and Energy sectors, to build a broad understanding of how the standards are applied across multiple industries, and see how the standards drive better design intent, clearer communication, and more efficient production.

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.
