Abstract：

For the problems of different CNC incremental forming methods with multi-feature models, the processing methods based on layer-first trajectories and feature-first trajectories were analyzed, and the advantages and disadvantages of the two processing methods were compared. Then, the forming process of plate under the two processing methods was simulated by finite element analysis software ANSYS, respectively. The results of finite element analysis show that the efficiency of CNC incremental forming method based on feature-first trajectory is 20.7% higher than that of CNC incremental forming method based on layer-first trajectory. In addition, the minimum thickness value after forming of sheet material based on the layer-first trajectory processing method is slightly larger than the minimum thickness value after forming sheet material based on the feature-first trajectory processing method. However, the contour of the formed sheet material under the layer-first trajectory is closer to the contour of designed part than the contour of the formed sheet material under the feature-first trajectory.
