A multi-level fuzzy comprehensive evaluation model and performance index system of on-line measurement system was established based on the theory of fuzzy.On the basis of test data, fuzzy evaluation matrix was obtained by using normal distribution fuzzification method, and the weight coefficient of each index was determined reasonably. Finally, the fuzzy theory was used to obtain evaluation results of all layers. Taking an on-line measurement system as instance,the feasibility of the evaluation method was demonstrated.Results show that the overall performance of this on-machine measurement system is good,with accuracy margin,and can be used to inspect parts on machine tools.
