| Abstract: | Based on the empirical fuzzy messages provided by the users and the maintenance technicians,using the fuzzy fault tree theory,the fault tree of the principal axis of the numerical control(NC) lathe was analyzed quantitatively,and the fault probability interval valuers of the principal axis under different confidence levels were calculated,providing a basis for the reliability design of the principal axis and the improvemcnt of the reliability level of the NC latlic. |
