Abstract：

To meet the needs of support fabrication for sheet metal CNC incremental reverse forming, a method of generating support die STL model whose size could be adjusted according to the processing requirement automatically from CAD model of sheet part was proposed. And the method for slicing the support die STL model according to the factors, such as the material thickness, tool length and so on was also presented. Meanwhile, the method of integral manufacturing and layered manufacturing for the support die was given. Finally, the case studied for the generation of support die STL model and the fabrication of support on 4-axis CNC milling machine was presented by taking a sheet workpiece with many complex surfaces as test model.
