GPS 100 - Introduction to Geometrical Product Specifications

I offer a free "Introduction to GPS" tutorial. It is about 90 minutes spread over 14 lectures and cover many of the topics explained here in more details: Introduction to GPS.

An explanation of the benefits of GPS and the difference between systematic GPS and traditional tolerancing.

  • The course explains why tolerancing needs have changed over time.
  • The shortcomings of traditional dimensional tolerancing and hybrid dimensional/geometrical tolerancing are explained using an easy to understand example.
  • The advantage of systematic GPS tolerancing is demonstrated in the same example.
  • The benefits for companies introducing systematic GPS tolerancing are summarised.

Geometrical Product Specifications(GPS) is the international symbol language used to express tolerances in technical drawings. It defines the nominal geometry of the components that make up the product, and the tolerances that quantify the allowable deviations from this nominal geometry.

The ISO-GPS language is defined in a number of ISO standards developed by ISO Technical Committee 213 "Dimensional and geometrical product specifications and verification".

I have been the chairman of ISO TC 213 since 2008.

Any time a design has to be captured and communicated, it is done using ISO-GPS. This global specification language enables a drawing of a component developed in one country to be sent to another country, where it can be understood and the component manufactured. ISO-GPS is an effective communications link, even when the designer and supplier do not have a common language. It helps products to be made more easily and efficiently, using fewer resources in the process.

Some of the more well-known ISO GPS standards are:
