| Abstract: | In this paper, we put finite element analysis up in allusion to multi point forming path for sheet metal, and applied it to the optimum deformation path design of contorted shape part. We applied the theory and method of the optimum deformation path to the technique for sheet metal in multi point forming, and adopted the approximative optimum path(the multi steps multi point forming) and the one step multi point forming to deform sheet metal. Comparing the deformation degrees of two kinds of deformation methods, we can investigate the effects of the multi steps and multi point forming methods on the deformation results. |
