Springback compensation for die face is the problem of die design for sheet metal forming.Firstly,a new designing method for springback compensation based on numerical simulation and die face compensation theory was introduced.Secondly,by means of an industrial twist blade,the precision of springback predicting was proved by experiment.Finally,the compensated die face of the blade was obtained after twice compensations.Subsequently,the bi-directional integrated design of "CAD→CAE→CAD" for die face was achieved by transforming the CAE into CAD model.
