Geometrical Tolerancing in Medical Devices

Practical training in geometrical tolerancing, tailored for medical device design.

Course Description:

This intensive programme introduces the fundamental principles of geometrical tolerancing, with a focus on the aspects most relevant to medical device design and manufacture. The course can be delivered to either BS 8888 & ISO GPS or ASME Y14.5 standards, depending on client requirements.

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 MedTech drawings and parts to see how the standards drive better design intent, clearer communication, and more efficient production.

Who it is for:

This course is designed to be accessible to newcomers to the standards as well as those with prior experience, within the MedTech sector.


The course is particularly valuable for:

  • Design and Mechanical Engineers

  • Inspectors and Inspection Planners

  • Drafters

  • Machinists, Operators, and Tooling Engineers

  • Sales, Purchasing, and Quality personnel

  • 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.

Materials provided:

  • Detailed course notes including drawing examples

  • Workbook with exercises and other printable handouts

  • Quizzes and knowledge checks to gauge progress throughout the course

  • Certificate of course completion


Delivery Format:

  • Onsite or online delivery


Duration:

  • 3 days
