In this paper a FE simulation of springback in reverse cup drawing process, taken from NUMISHEET’99 benchmark is carried out, utilizing commercial code, ABAQUS. The forming process is simulated in ABAQUS/Explicit while the springback simulation is performed in ABAQUS/Standard. The utilized method is probing a relationship between the springback and other important factors such as initial blank thickness die gap and type of material, i.e. Aluminum alloys and HSS. It will be shown that increasing the initial blank thickness and decreasing the die gap leads to springback reduction in the cup. Considering the required maximum punch load for different values of initial blank thickness and die gap reveals that these parameters should be controlled appropriately. Moreover, comparing the obtained results shows that the sheets produced from HSS exhibit smaller amount of springback after unloading, however, they require much larger punch load during the forming process.
