The traditional reliability models of CNC machine tools are based on the assumption that the machine after repair is as-good-as-new or as-bad-as-new. But it is not the precise model compared with the Engineering practice. This article focuses on the repair degree to the sub-system of CNC machine tools, and the reliability modeling method was proposed based on incomplete repair circumstances, considering the maintenance degrees. Meanwhile, the model’s parameters are calculated using the method integrating maximum likelihood method. Genetic algorithm is used in the solving process. The model is applied to actual data, the results shows that: this model can get the maintenance degrees which reflecting the real states of each sub-system’s changes and the intersection of the different failure-periods. It can be the references and basis for the design of reliability and maintainability.
