摘　　要：针对航空发动机叶片形状复杂、加工精度高的特点,在ACIS几何平台上采用截平面法进行刀轨规划,变步长法控制加工精度,刀轴矢量自动调整法避免干涉,反变形补偿法控制加工变形,实现了叶片主面及阻尼台无干涉加工,并开发了航空发动机叶片五轴铣削加工计算机辅助软件。与通用CAM软件相比,该软件具有针对性强、操作简单、走刀路径更优化、对阻尼台的加工处理更方便等优势。The shape of aeroengine blades is complex,and the require of machining accuracy is high.To solve those problems,a tool path planning algorithm is realized based on ACIS.In this algorithm,tool path is generated by section method.The machining accuracy is controlled by variable step length.The interference is avoided by adjusting tool shaft.The machining deformation is compensated by anti-deformation compensation method.A CAM software is developed to mill blades by 5-axis processing method.Compared with the general CAM software,the software is more special and operation is simpler,the tool path generated by the software is more optimized,the damper processing by the software is more convenient.
