N2 - The reliability evaluation indices of computer numerical control (CNC) machine tool system have many levels and characteristics. In this paper, the CNC machine tool system is regarded as man-machine system. And the fuzzy comprehensive evaluation method is used to consider the influence of the reliability of the CNC machine tools and the operators on the system reliability. First, an evaluation index system is established and the criteria layer and the indicator layer are determined. Then, the weights of the indicators at each level are calculated by expert scoring. And finally, a comprehensive evaluation score is obtained through step-by-step evaluation. Taking JW4050AL machining center as an example, the results show that the reliability of this type of machine tool is at a high level, which is consistent with the actual situation. The results show that this method is suitable for the reliability evaluation of CNC machine tools.
