Abstract：

On the basis of sheet metal incremental forming process, combining with the characteristics of CNC forming hammer incremental forming process, the incrementally pressing forming (IPF) process could be carried out through changing the trajectories of the incremental forming, dispersing the points on the contour into interpolation points on the sine curve and making the tool-head jump movement regularly on each layer. On the NC incremental forming machine, the 65 ° angle of fixed round mouth cup and the square mouth cup were formed by incrementally pressing forming process. The results show that the trajectory modified by this method can be processed on the NC incremental forming machine. Therefore, the feasibility of the incrementally pressing forming process is validated, and this method can be used for trajectories with different shapes.
