1. Definitions
GPS (Geometrical Product Specification – ): set of ISO standards used to define requirements related to product geometry, as well as those related to measurement systems used for verification purposes.
Nominal geometry of a part: set of surfaces bounded by portions of simple geometric surfaces (planes, cylinders, cones, spheres, tori) or complex geometric surfaces (e.g., Bézier surfaces).
It is defined either by conventional drawings (2D drawings) or by a digital model, 3D model (CAD model).
Nominal geometric feature: point, line, or surface that is related to the nominal geometry of a part.
The surface of a...
