Influence of different pre-hem paths on the flange geometry was studied first. According to the results of simulation the vertical pre-hem path was applied. Effects of the process parameters including pre-hem angle, flange length and friction coefficient on Roll-in/out were also investigated in this paper. Results of the simulations show that roll-in values decrease with pre-hem angle increasing and increase with flange length and friction coefficient increasing. And in the case of 6×45° leads least hemming force.
