摘　　要：分析了数控加工中各种三维区域清除粗加工策略和半精加工、精加工策略,总结了各种加工策略的适用范围与优劣性。分析与解决了五轴数控加工的参考曲面设计规则、切入切出、过切与碰撞等典型问题。以典型零件的五轴数控加工为案例,分析与制订了加工工艺,确定了粗精加工策略,并评价该案例的加工质量。Presented an analysis on various schemes for elimination of rough machining within 3-D area and on semi-finishing/finishing tactics while summarizing the applicability oI various machining tacucs including their advantages and disadvantages. It also provided the analysis and solution for typical problems such as the design rules for reference surface to be processed by 5-axis CNC machine, the cutting-in and cutting-out, overcut and collision. In the case of typical parts processed by 5-axis NC machine, its processing technique was analyzed and developed, the rough finishing tactics was determined with a case study of the processing quality.
