@@@@Under the conditions that the stamping process parameters and material parameters were determined,taking the U-shaped piece forming in international conference NUMISHEET'93 as the study object,it was simulated by using Dynaform software, the simulation results were compared with the results given in conference to verify the model feasibility. Then through orthogonal exper-imental design,radial basis function agent model was established to make springback prediction of sheet metal forming. Using MAT-LAB,its optimal solution was obtained. So the feasibility of the proposed method is verified.
