摘　　要：为提高离心式叶轮叶片的加工质量和效率,在粗加工阶段,通过考虑叶轮粗加工路径规划策略、刀具轴向规划方式以及碰撞检测与修正方法,提出离心式叶轮五轴粗加工优化。最后以具体叶轮为例,采用UG NX4.0进行建模与数控编程,经过Vericut分析并进行刀轨优化及仿真,通过加工路径的比较,对加工效率进行量化分析,结果证实了数控加工程序在后能大大地提高效率,并且能有效地指导编程员采用最合理的加工参数,服务于实际生产。In order to improve the quality and efficiency of centrifugal blade in stage of rough milling, this article will provide an optimal rough milling method, which focus on the tool path planning of the centrifugal blade rough milling, the planning of tool axis direction, the rule and revision rule of collision and checking. The NC programming and CAD model was built by UG NX4.0 and simulating and analyzing by VERICUT. The results show this optimal method can give much better quality and greater efficiency than the traditional manufacturing method by Vericut optimization,and it can effectively help programmer to use the optimal parameters, and then serve to the real manufacture.
