| Abstract: | There are the springback during metal sheet forming,so metal sheet parts can not meet the requirements.This paper focusing on the case of the actual workpiece springback,through the finite element CAE methods,discusses the force before forming,coefficient of friction,clearance and other main factors on the springback effect,and puts forward several methods of reducing the springback.The effect is good that verified by the practice. |

| Keywords: | springback the force before forming coefficient of friction clearance arc rib |
