Abstract

In the present paper, some models for simulation the multipoint process of deformation using the finite element method were developed. The models were designed based on a program for contact points calculation between the part and the tool active elements. The localization of contact points is analyzed. For a fixed rigid configuration of the multipoint deformation tool without interpolator, the correlation between the contact points distribution and localized deformation is discussed. In the case of a flexible configuration of the multipoint deformation tool with interpolator the part quality is analysed in terms of surface quality, part profile deviation and elastic recovery. The results show the presence of spring forward which increased when the part profile angles are increasing, to the same interpolator thickness.
