Unformatted text preview: positioning deviation of the workpiece is the object of the present paper. 182 … F. Villeneuve and F. Vignat Set-up k-1 Unification of connections contribution to obtain positioning deviation Deviation part,surfacei = − Deviation machine,part + Deviation machine,surfacei • MWP Set-up k Unification of connections contribution to obtain positioning deviation Deviation part,surfacei = − Deviation machine,part + Deviation machine,surfacei • MMP Figure 2; generation of the MMP Each set-up simulation defines a MWP (Model of Workpiece) built around the nominal model of the part. For set-up n, the MWP built at the end of set-up n-1 is virtually positioned on the part-holder of set-up n to obtain the positioning deviation in set-up n. (fig. 2). This operation must be repeated for each set-up until the final part is virtually manufactured. The defects collected in the MMP at each set-up are classified in 3 categories: • Parameters of deviations of the surfaces of the part-holder (DH). • Parameters of deviations of the manufactured surfaces (surfaces swept by the cutting-tools)...
