GPS 110: Dimensional Tolerancing Course |
The list price for the course is US$ 99.
This course covers dimensional tolerancing within GPS:
- How dimensions are indicated in technical drawings
- The different types of dimension indications
- What should and what should not be toleranced with dimensional tolerances
- IT tolerance codes according to ISO 286
- The envelope requirement
- Former rules for dimensional tolerancing
The course covers dimensional tolerancing in technical drawing according to the ISO GPS rules. It explains the feature concept and defines features of size, which are the only kind of features that should be toleranced with dimensional tolerances.
The course explains how dimensions and tolerances are indicated in drawings. It covers tolerancing using IT (International Tolerance) codes, e.g. H7 or c6, as defined in ISO 286.
The course covers the envelope requirement that is used to ensure simple assemblability between shafts and holes.
Finally, the course discusses former practice and the rules that applied before the most recent standards for size tolerancing were published in 2010 and explains why dimensional tolerances should only be used for features of size.
The goal of this course is to give the student an understanding of the possibilities and limitations of dimensional tolerancing. By taking this course you can learn how dimensional tolerances are indicated in technical drawings, how to look up IT tolerance codes in ISO 286 (the standards are not included in the course materials), how the envelope requirement works and what the former practice and rules were before the latest ISO standards for dimensional tolerancing were published in 2010.
This course is intended for anybody working in manufacturing industry, who has an interest in dimensional tolerancing according to ISO Geometrical Product Specification standards.
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.
The primary ISO GPS standards for dimensional tolerancing are:
