Abstract: Many parameters are effective in deep drawing process. Some of these parameters that influence the deep drawing process are the tool geometry, the friction coefficient and the drawing force, which cause the breakup and wrinkling in the axisymmetric duct containers' deep drawing process. In this paper, at the beginning, a basic theory of deep drawing and also a review of various methodologies formulated for finite element modeling of deep drawing were presented. Then, a numerical model was developed to investigate the effects of the friction coefficient and geometric parameters on the maximum drawing force in forming sheet metal SPXI250 under simple cylindrical deep drawing conditions by finite element (FE) simulation done using ABAQUS / EXPLICIT software. The required force for forming was examined in this paper. The results of simulations show that a change in the friction coefficient between interface surfaces leads to a significant difference in the punch's maximum drawing force and reduces the breakthrough in the blank, and also the effect of the matrix radius on the drawing force is more important than the The effect of the punch rim radius. The results of this paper were compared with Sieble's theory and experimental experiments and with the results of other researchers. There was a high level of agreement between the findings of this study and the findings of other researchers.
