REMINDER OF THE METHOD The method exposed in [Villeneuve et al., 2004] is based on the determination and the analysis of the deviations of the surfaces of a part relative to their nominal position (nominal part). The method is developed in two steps: • The first step determines the effect of the process in term of deviation of the surfaces of the part. At the end of this step, a model of the manufactured part with deviation defects is generated (it will be called MMP for Model of Manufactured Part). • The second one consists in analyzing, using the MMP, the consequences of the process on the respect of the functional tolerances (analysis) and transferring these tolerances in manufacturing tolerances. Simulation of the Manufacturing Process 181 Figure 1; process deviations The deviations of the surfaces of the MMP are expressed relative to their nominal position in the part (nominal part). These deviations are expressed by a small displacement torsor plus the variations of the intrinsic characteristics of the surfaces (di...
