Summary

This introductory course provides an essential understanding of dimensioning and tolerancing and the symbolic language of GD&T within BS 8888.

BS8888 Technical Product Documentation and Specification is the UK national standard for producing mechanical part technical drawings and CAD models. Originally named BS 308, it has undergone a series of revisions resulting in the latest version BS 8888:2017.

The course will bring you up to date with the latest version of BS 8888, including the meaning of design intent; how mechanical parts are dimensioned and tolerance within the standard in order to meet design intent and avoid ambiguity of specification; symbology, datums and geometrical tolerances; and the relationship to ISO GPS standards such as ISO 8015, 5459, 1101, 5458, 2692 etc.

It is supported with demonstrations, models, case studies, questions, exercises and calculations. You are encouraged to bring your own questions to the course. 

Who should attend?

This course is suitable for anyone who creates, edits or reads mechanical engineering part drawings to the UK national standard BS 8888, such as mechanical engineering designers, drafters and checkers, manufacturing and quality engineers, technical managers, technicians, machinists, toolmakers and inspectors.
