GPS 100 — Introduction to Geometrical Product Specifications
Free — about 90 minutes spread over 14 lectures. Available at iso-gps.com ↗.
An explanation of the benefits of GPS and the difference between systematic GPS and traditional tolerancing. Covers why tolerancing needs have changed, the shortcomings of dimensional tolerancing, and the advantages of systematic GPS. A good starting point for anyone new to GPS.
GPS 110 — Dimensional Tolerancing
US$ 99. Available at iso-gps.com ↗.
The basic rules for 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
GPS 120 — Introduction to Geometrical Tolerancing
US$ 99. Available at iso-gps.com ↗.
An introduction to geometrical tolerancing within GPS, with easy-to-follow examples using each of the 14 geometrical tolerancing symbols. Covers form, orientation, location, profile, and runout tolerancing, and includes an introduction to datums.
GPS 121 — Degrees of Freedom Analysis
Free. Available at iso-gps.com ↗.
Introduces the Degrees of Freedom (DoF) indicator — a visual tool for analysing how a tolerance zone constrains the toleranced feature. Covers cylindrical and planar tolerance zones, datum systems, and adding constraints to tolerance zones. A bridge course between GPS 120 and GPS 122/123.
GPS 122 — Tolerance Zones
US$ 99. Available at iso-gps.com ↗.
Tolerance zones are the building blocks of geometrical tolerancing. Covers all tolerance zone shapes defined in ISO 1101 — parallel planes, cylinders, spheres, free-form surfaces, and 2D cross-section zones — and how constraints limit their movement. Builds on GPS 120 and GPS 121.
GPS 123 — Datums and Datum Systems
US$ 99. Available at iso-gps.com ↗.
Datums and datum systems constrain tolerance zones by locking degrees of freedom. Covers datum indication (simple datums, partial-feature datums, datum targets, common datums), datum association, datum systems, and Theoretically Exact Dimensions (TEDs). Builds on GPS 120, GPS 121, and GPS 122.
