In order to explore the influence of friction coefficient on the dimensional accuracy of workpiece in multi-step ironing, the finite element simulation of multi-step ironing process was carried out. Then, in the finite element simulation software Simufact.forming, low carbon steel C15-c was selected as the test material, and the friction coefficient was taken as the test parameter to carry out three-step ironing numerical simulation. Furthermore, the influence of friction coefficient on the forming quality of workpiece in multi-step ironing was studied by taking the actual outside diameter and wall thickness deviation of cylindrical part after three-step ironing as the evaluation indexes. The results show that the actual outside diameter and wall thickness of workpiece are smaller than theoretical values after multi-step ironing. With the increasing of friction coefficient, the outside diameter of workpiece increases first and then decreases, while the wall thickness deviation decreases first and then increases. When the friction coefficient is 0.12, the actual outside diameter of workpiece is the closest to theoretical outside diameter, and the wall thickness deviation of workpiece is the smallest.
