In this course you will learn about all the 14 geometrical tolerancing symbols that are used within GPS through easy to follow examples.
You will also receive a brief introduction to datums, sufficient for you to understand the use of datums in the examples.
The course is an introductory course aimed at those without any background in geometrical tolerancing. You will receive a basic understanding of how geometrical tolerancing works, what each of the tolerancing symbols means and how the tolerance zones are defined, allowing you to get started with geometrical tolerancing. You should consult the ISO GPS standards listed below for the complete rules for geometrical tolerancing.
The course is based on ISO 1101, ISO 1660 and ISO 5459.
The course gives examples of all the sub-types of geometrical tolerancing, including:
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".
This is a basic course that will get you started with geometrical tolerancing. It does not provide all the details and rules that apply in every case. This would require a much more extensive course.
