在对平面、型腔和曲面等加工面的各种主要走刀轨迹模式进行系统归纳与分析的基础上，提出了走刀模式评估的主要指标，并应用模糊多目标评估方法解决了定性、定量指标同时存在情况下的方案评估问题，最后以波轮数控加工的三种走刀模式作为实例，实现了其加工方案的评估排序 Based on the systematic induction and analysis of all the major path patterns of the machining surfaces, such as plane, cavity and curved surface, the main indexes of toolpath mode evaluation are proposed. The fuzzy multi-objective evaluation method is used to solve the problems of qualitative and quantitative Index at the same time the case of program evaluation problems, the final wave of CNC machining three kinds of take the knife as an example, to achieve the assessment of the processing scheme ranking
