| Abstract: | Aiming at the effect of definite ending time on CNC machine tools, the failure time was determined by using the total failure time method in this paper. The test date and the relevancy of the referenced distributions were obtained by using the gray correlative analysis method to solve the problem of a passel of date matched with various distributions. According to the relevancy, the optimized distribution model was confirmed. An example of a real operation process was demonstrated by using the field ending data from four CNC machine tools, which showed that this method was feasible and simple. |
