Control procedure for the dimensional measurement of cast parts

A procedure in which the raw parts and the finished cast parts were initially defined in a file with the aid of computer-aided design (CAD), principally characterised in that it comprises the following steps: - positioning of the part on a support and localisation of the latter in space (101), - selection of the areas to be controlled (102), - analysis of shapes on the basis of data processing means (103), of three-dimensional measurement means and of control means, consisting for each area selected in: . producing three-dimensional measurements, . storing these measurements points in memory, . comparing the measurement points with the definitions given by the CAD file, then, when all of the areas have been analysed: - accepting or not accepting the part on the basis of all the comparison results (112, 113).
