Abstract：

Backward spinning is analyzed by 3D rigid-plastic FEM. A 3D mechanical model for backward spinning is presented in this paper. The distributions are obtained of strain-rate and sterss in the contact area of the roller and its adjacent area. The results can well interpret the principle of backward spinning deformation. The relationship between the roller angle and three components of spinning force has been found out,and the optimum roller angle,when the general spinning force gets to the minimum va1ue, is calculated. The distributions of deformation area obtained by FEM agree with the experimenlal result well.
