The Geometric Product Specification (GPS) and Geometrical Dimensioning and Tolerancing (GD&T) languages are the most powerful tools available to link the perfect geometrical world of models and drawings to the imperfect world of manufactured parts and assemblies. Therefore, technicians, designers and engineers need a symbolic language that allows them to define, in a complete, clear and unambiguous way, the admissible variations, with respect to the ideal geometries, in order to guarantee functionality and assemblability, and to turn inspection into a scientifically controllable process. Designers create perfect and ideal geometries through drawings or by means of Computer Aided Design systems, but unfortunately the real geometrical features of manufactured components are imperfect, in terms of form, size, orientation and location. Moreover, the differences between ISO GPS and the American ASME Y14.5M standard are shown as a guide and reference for the drawing interpretation of the most common dimensioning and tolerancing notations. This book is intended for designers, process engineers and CMM operators, and it has the main purpose of presenting the ISO GPS rules and concepts.
