Abstract
In the five-axis milling process, the existing cutter axis vector planning only adjusts the cutter axis vector and neglects the effect on the cutting bandwidth. Considering this problem, a method of adjusting the cutter axis vector by contrasting the change rate of the cutter axis vector is proposed, which not only ensures the cutting bandwidth but also keeps the change of the cutter axis vector smooth. At the same time, the effective cutting shape and the calculation method of the cutting bandwidth of the flat-end cutter in the feed direction are described. The influence of the change of cutter attitude on the cutting bandwidth is expounded, and the optimal cutter axis vector position is proposed. The MATLAB software is used to simulate and compare the changes of the cutter axis vector before and after optimization. It shows that the algorithm can effectively improve the processing efficiency and processing quality of the curved surface.
