数控车削参数的多目标优化方法研究

Research on Multi-objective Optimization Method for NC Turning Parameters

以表面粗糙度、刀具磨损、材料去除率作为研究目标,运用田口方法正交表建立实验,借助模糊理论,将车削参数对应于各目标关系,建立语意性规则,探求各目标的相对关系。对求得的最优切削参数进行切削实验,验证了优化的切削参数的适用性,从而为设计制造提供有益的参考。

Based on the surface roughness, tool wear and material removal rate, the orthogonal experiment of Taguchi method was used to establish the experiment. By using the fuzzy theory,the turning parameters were corresponded to the target relations,the semantic rules were established. The best cutting parameters are obtained by cutting experiments, and the applicability of the optimized cutting parameters is verified, so as to provide a useful reference for design and manufacture.
