Springback is one of the key factors to influence the quality of drawn sheet metal parts in deep drawing process. Previous investigations about the springback have shown that, the amount of work-piece deformation can be affected by this phenomenon in the deep drawing process. Therefore, to optimise this manufacturing process and to increase the dimensional accuracy of the parts, it is essential to find out the effective parameters and bring the deep drawing process under producer control. In this paper, the finite element analysis of springback was applied and the effects of many physical parameters on the springback such as, type of materials, blankholder force, coefficient of friction and tool clearance were studied. Then, it was proposed how to decrease the effect of springback for different materials. For simplicity, two dimensional analyses (plane-strain simulation) were performed and the results were compared with experimental data. A good agreement was found between numerical and experimental results.
