Abstract：

Because the continued push of the forming tool to the blank in the incremental forming process, the blank was distorted and the dimensional accuracy of parts was affected. To reduce the distortion of parts and improve the forming precision, taking square cone-shaped part for example, the regulation of deformation was studied by means of finite element numerical simulation, and the influences of parameters on distortion were studied by the single factor analysis method. The results show that the bottom and side wall of part are distorted to some extent. With the increase of forming depth, the position of the maximum distortion displacement is close to the middle part,and the distortion occurs parabola distribution along the lateral wall finally. Furthermore, the distortion of parts increases with the decrease of tool radius and the increase of layer spacing. The results show that the distortion of parts can be reduced and the precision can be improved by changing the tool radius and layer spacing.
