摘　　要：在叶片加工中,由于进出汽边曲率变化大,导致刀轴矢量变化剧烈,常常会出现过切现象。为解决该问题,提出了一种刀轴矢量插补优化算法,在线性插补的基础上,对相邻插补点插补矢量进行优化;利用JAVA语言开发了集成矢量优化算法的后置处理软件;仿真和实验结果验证了该算法的正确性,有效地解决了叶片在加工过程中进出汽边的过切问题,从而提高叶片的加工精度。Over-cut was presented in the blade inlet and outlet sides due to changes of blade curvature during in five-axis machining. Aiming at solving that problem. Based on the linear interpolation,an optimization algorithm of tool vector interpolation for the adjacent interpolation points is proposed in this paper. The post-processor with vector optimization function is developed using JAVA language. Results of simulation and experimental verify the correctness of the algorithm,thereby improving the processing accuracy of the blade.
