| Abstract: | Spring-back is a technical problem that is ordinary but is also difficult to control in metal stamping processing technique,especially for the multi-angle U-shaped part.Based on orthogonal experiment,the forming process of the specific part and the result are simulated by using DYNAFORM.It’s significant for guiding designers to work out the production technique of similar parts. |
