Abstract：

In the CNC incremental forming with multi-directional adjustment of sheet metal posture, in order to solve the planning problem of tool moving direction relative to the difficult forming surface and the easy forming surface, the influences of different tool moving directions of tool head on forming quality were studied. For the model of forming parts with the difficult forming surface and the easy forming surface, taking the three tool moving directions of tool heads in the same direction, reverse direction and forward and reverse alternate direction as the research objects, the influences of different tool moving directions on the contour dimension and material flow of forming parts were analyzed by the finite element analysis and mesh forming experiment. The results show that the difference degree contour between forming part and designed part formed by different tool moving directions is in the order of the same direction, reverse direction and forward and reverse alternate direction from large to small. However, the distortion degree of the sheet metal formed by different tool moving directions is in the order of the same direction, reverse direction and forward and reverse alternate directrion from large to small.
