Abstract：

For the problem that the complex sheet metal parts, whose surfaces are invisible along the positive direction and negative direction of Z-axis with forming angle more than 90 degrees, cannot be formed by the three-axis CNC incremental forming process, a new compound forming method was proposed based on three-axis CNC incremental forming and five-axis CNC incremental forming. Considering the forming efficiency and formability, the shape features were divided into the features which could be formed by three-axis CNC incremental forming and five-axis CNC incremental forming respectively, and then the three-axis CNC incremental forming and five-axis CNC incremental forming were carried out. According to ANSYS/LS-DYNA , the finite element analysis and the actual forming experiment show it is feasible that the complex sheet metal parts which are invisible along the positive direction or negative direction of Z-axis can be formed by the compound forming method based on three-axis CNC incremental forming and five-axis CNC incremental forming.
