Abstract:

In order to evaluate each performance index of a numerical control machine tool, the comprehensive performance evaluation index system of a numerical control machine tool was established, and the performance index weight coefficient of the numerical control machine tool was determined by using the 1-9 scale law in the analytic hierarchy process. Taking a numerical control 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.

Key words: numerical control machine tool; comprehensive performance; analytic hierarchy process; fuzzy comprehensive evaluation
