摘要/Abstract

摘要： 复杂曲面加工常采用统一的切削参数和刀具路径完成整个曲面加工，未考虑复杂曲面几何特性变化对能耗和加工时间的影响关系。以复杂曲面为研究对象，根据曲面曲率特性并运用模糊聚类算法对复杂曲面进行分区。在此基础上，针对每一个分区曲面，采用正交试验方法确定能耗和加工时间综合最优的切削参数和刀具路径,即实现复杂曲面加工总能耗最低和加工时间最短。最后，将所提出的曲面分区铣削优化方法与传统曲面整体铣削方法作对比，验证了所提方法的有效性。

Abstract: Traditionally, the workpiece complex surfaces were machined by a specific cutting parameters and toolpath. In fact, the dynamic curvatures of complex surfaces had major impacts on energy consumption and machining time. The workpiece complex surfaces were partitioned into several patches according to the characteristics of surface curvatures and by using fuzzy clustering algorithm. Then for each patch, a set of orthogonal experiments were designed to determine the optimal cutting parameters and toolpaths aiming to minimize the machining time and energy consumption. Finally, the effectiveness of the proposed method was demonstrated through comparison of the partitioned complex surface milling and the traditional whole complex surface milling.

Key words: partitioned complex surface, milling, energy consumption, cutting parameter, toolpath
