Unformatted text preview: oud data model. The 3D CAD model stores the tolerances specifications defined by the designer as well as the specification of the inspection methods. The points cloud model is a complete representation of the manufactured product and it is defined by the digital acquisition of the real product. The acquisition phase is performed with non-contact techniques to ensure high performances in terms of speed. The information stored in the CAD model is used to select and drive the different inspection procedures to be performed on the acquired data. Keywords: Geometrical Tolerances, Automated Inspection, Feature-Based Model, Reverse Engineering 1. INTRODUCTION The Geometrical Tolerances (GT) inspection of mechanical components (sheet-metal components, injection molded components, machined components, etc.) is aimed at measuring if the relevant geometrical features of a product, defined during the design phase and represented by dimensionally constrained geometries, have been manufactured with the...
