Davidson (ed.), Models for Computer Aided Tolerancing in Design and Manufacturing, 301 – 310. © 2007 Springer. 302 G. Cid et al. Our work belongs to a different approach that consists in determining geometrical behaviour of a mechanism in a symbolic writing. Moreover, in this paper we present the way we include actual geometry variation in our model. After a presentation of this integration of actual geometrical variations, we present how we take deformation into account in our simulation. Then, this method is illustrated through an industrial study. 2 INTEGRATION EQUATIONS OF ACTUAL GEOMETRIC DEVIATION IN 3D Geometrical definition of a mechanism is defined through numerical models of its components using CAD system. The geometry of actual components does not exactly match the numerical geometry. The simulation of the behaviour of the mechanism that includes geometrical deviations is necessary. Geometrical deviations belong to two types. The first...
