چکیده:

Deep drawing is one of the important sheetmetal forming processes. By using this process, many parts are manufactured in industries. This process is influenced by many parameters. In this paper, the effects of friction coefficient and tool geometry on the changing of the wall thickness in SPXI250 alloy sheet of the axisymmetric hollow containers were investigated by simulation using finite element method (FEM). The finite element simulation of deep drawing process was done by using ABAQUS/EXPLICIT software. The results of simulations show that a change in friction coefficient between interfaces of different parts of the die and the blank lead to a large difference on the wall thickness. Also it shows the effects of the matrix radius on the final wall thickness are more important than the effects of the punch rim’s radius. The results of this study were compared with the results of the other researchers and with experimental tests. There was a high level of agreements between the findings of the present study, experimental results and those of the previous which confirmed the results of this study.
