Turning Ideas into Reality with GPS
Online Training Catalog
This is 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.
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 contains easy to follow examples using each of the 14 geometrical tolerancing symbols. It gives examples of all the kinds of geometrical tolerancing, including:
- Form tolerancing
- Orientation tolerancing
- Location tolerancing
- Profile tolerancing
- Runout tolerancing
The course includes an introduction to datums that allow students to understand the use of datums in the examples.
Live in-house GPS training
To begin the implementation of systematic GPS, most companies start with training that take their staff to a sufficient level of expertise to express functional requirements with GPS in the case of designers, and to read and understand systematic GPS drawings in the case of the staff that reads drawings in their work. The typical target groups for this training are designers, manufacturing and process engineers, metrology and quality personnel, and purchasing.
I have an off-the-shelf training package that covers most aspects of GPS in 3 days. It can be tailored to your needs by adding and removing modules to fit how you want to implement GPS.
The training package consists of the following modules:
- The GPS Matrix System
- Dimensional Tolerances
- Tolerance Zones
- Datums and Datum Systems
- Related Tolerances
- Unrelated Tolerances
- Basic Example
- Form Tolerances
- Combination of Size and Geometrical Tolerances
- General Tolerances and Special Drawing Indications
- Surface Texture Tolerances
- The IfGPS 8 Point Tolerancing Procedure
The training combines covering the meaning and use of all but the most obscure of the tolerancing symbols as well as systematic application of GPS, which really is what gives you the significant advantage of using GPS.
The training can be supplemented with workshops, either as part of the same session or as a separate session once the students have had some time to apply their GPS skills. In the workshops we typically take one of your products or a set of components and go through the process of tolerancing them, while discussing the tolerancing decisions along the way. This teaches the systematic application of GPS and the thought process that goes into systematically tolerancing components, so they will function together.
Additional training Subjects:
Which surfaces on the component interacts with other components and which ones determine the location and orientation of the component in the product.
Tolerance stack-up analysis
What is the expected total variation you should expect to see in the product, given a certain set of tolerances for the individiual components, or what should the tolerances for the components be, if you want to limit the total variation to a given value.
GPS for Production
Converting the tolerancing for the finished component into tolerancing for the individual process steps in the manufacturing process. Determining which tolerances are secured by the choice of machine tools and which ones have to be monitored during production.
GPS for Verification
Often it is not possible to measure GPS tolerances exactly as they are defined. But with knowledge of the production process, it is often possible to use simplified verification methods to ensure the quality of the components.
