Abstract：

In order to overcome the problems that the traditional integral support could not be reused and the process of the integral support based on CNC (Computer Numerical Control) milling or 3D printing cost a long time and consumed excessive materials, a new method of CNC incremental negative forming combined support device based on 3D printing was proposed. The combined support device could form different shapes of sheet metal parts by only changing the die curve surface plate and different heights by changing support parts to adjust support height. Furthermore, the structure and working principle of the combined support were given, and an actual support was conducted. Based on the combined support of forming, the experimental results show that the combined support is of applicability.
