An intensive four-day course introducing the fundamental principles of Geometrical Product Specification (to BS 8888 and relevant ISO standards).
Discover how the system of geometrical tolerancing works.
Find out how to annotate drawings correctly
Learn how different types of tolerance control different characteristics, and how to choose the right tolerance for your application.
Start to benefit from a better standard of specification.
This incorporates in full the contents of our most popular course, Geometrical Tolerancing to BS 8888 & ISO Standards – Level 1, with the addition of modules to cover 'specification format and presentation', 'surface texture' and 'edge tolerances'.
The course uses examples of your own drawings or products, where available, to illustrate some elements of the course material, and as the basis of some worked examples.
Duration
4 days (available for classroom or on-line delivery).
Who is it for?
Mechanical, production and design engineers, drawing office and inspection personnel.
Some familiarity with engineering drawing practice and conventional dimensioning and tolerancing is required.
