Abstract：

The forming principle and deformation analysis of NC incremental sheet metal forming process were presented.The process planning,the experiment and the main process parameters of vertical wall square box forming were investigated.The deformation of sheet metal was only made around the tool head and the deformed region was subjected to stretch deformation.Therefore,the sheet metal was thinned,surface area was increased,and sheet metal forming point-by-point led to the whole sheet deformation.The forming half-apex angle θ and corner radius r were the main process parameters of vertical wall square box in NC incremental forming.According to Sine Law,a vertical wall square box can not be finished by NC incremental sheet metal forming process with a single tool-path,it must be formed with multi tool-paths.Thus,the parallel line type tool path process method was presented to make the vertical wall square box,and experiment and analysis were made to verify it.
