| Abstract: | The principle of multi-point forming(MPF)technique has been presented.Impressed mark,one of the most important defects during the process of square cup has been discussed by means of numerical simulation on the as-pects of drawing shape,thickness,and material of sheet met-al.Based on the simulation results,the reasons and control methods of impressed mark have been pointed out with ex-periment on the multi-point die forming of square cup by the MPF machine,to validate the efficiency of the numerical sim-ulation. |
