Finite element method was used to simulate the shaft cold drawing process . By means of orthogonal experi- mental method to investigate die structure parameters （ the semi - angle of drawing dies or, the transition arc radius R, the length of bearing part L,I ） on the impact of cold - drawn shaft. As a result, the optimal parameter combination were ob- tained under the minimum drawing force , minimum radial stress and the minimum equivalent residual stress conditions which are a = 5 o, R = 5 mm and Ld = 4 mm. Based on what was mentioned befor...
