Geometrical Tolerancing - Advanced User Programme
What is it?
The ultimate training programme for the designer or engineer who needs an in-depth understanding of the system of geometrical tolerancing (to BS 8888 and ISO standards).  This intensive five-day course incorporates all five geometrical tolerancing modules.
  • Discover how the system of geometrical tolerancing works.


  • Learn the correct way to annotate drawings
    • .

  • Find out about the different types of tolerance and the characteristics they control, and a systematic approach for choosing the right tolerance for your application.


  • Discover the benefits of the Maximum Material Principle
    • .

  • See how different operators can be used to develop precise control over tolerance characteristics and the manner in which they are inspected, and learn which are the default operators for each characteristic.


  • Learn the formal methodology for carrying out tolerance stack calculations on parts and assemblies.
Duration
5 days.

Who is it for?
Mechanical, design and production engineers.

Familiarity with engineering drawing practice and conventional dimensioning and tolerancing is required.
