Abstract：

In order to overcome the issues in the CNC incremental negative forming such as extreme depth of the part, insufficient length of pressing tool, thin thickness of the support part, and interference between pressing tool and sheet, a sectioning and staging forming method was proposed, which forms the sheet metal part by sectioning the sheet metal part model with the support part. At the same time, the sectioning and staging forming process was given. The feasibility of the method was analyzed by digital simulation, and a practical sheet metal part was fabricated through the forming experiment. The results show that the sectioning and staging forming technology can be applied in the fabrication of sheet metal parts.
