In this paper, we present the simulations of thin sheet metal stamping process in the PAM-STAMPS framework to investigate the effect of the stamping (die) velocities on the stamping force. The aluminum alloy A1050 is adopted as the working material in the simulation. The simulations are conducted for various thicknesses of the blank (t = 1, 1.2, and 1.5mm), and the different of the stamping speeds (v = 5, 10 and 15 mm/s). The diameter of the blank is 110mm for all simulation cases. The simulation results reasonably predict the residual stress, stamping force, the forming limit diagram of the material and thickness distributions along the workpiece. The blank thickness increases then the stamping force also increases. The simulation results also show that the stamping (die) speeds do not significantly affect the stamping force.
