基于层次分析法的数控机床性能模糊综合评判

为了全面评价数控机床的各项性能指标,建立了研究数控机床综合性能的评价指标体系,采用层次分析法中的1～9标度法确定了数控机床各项性能指标的权重系数。以某型数控机床为研究对象,运用模糊综合评判法对其各项性能指标进行评价研究,结果表明该机床的综合性能较好。分析认为可通过改进重复定位精度、脉冲当量、主轴转速这三项性能指标来进一步提高该数控机床的综合性能。

Fuzzy comprehensive evaluation for the performance of a numerical control machine tool based on the analytic hierarchy process

In order to evaluate each performance index of a numerical control machine tool, the comprehensive performance eval-uation index system of a numerical control machine tool was established, and the performance index weight coefficient of the nu-merical control machine tool was determined by using the 1-9 scale law in the analytic hierarchy process. Taking a numerical con-trol machine tool as the study object, each performance index of the numerical control machine tool was studied by using the fuzzy comprehensive evaluation. The result indicated that the comprehensive performance of this numerical control machine tool was good. The analysis showed that the comprehensive performance of this numerical control machine tool could be further enhanced, when the index performances of repetition pointing accuracy, pulse equivalent and spindle revolution were improved.
