| Abstract: | The researches on product lifetime distribution model are the basis of assessment and improvement of product reliability level. The reliability field test at machining centers was carried out and the failure data were collected. After analyzing and processing these data by using the methods of curve fitting and hypothesis test, the lifetime distribution model of the machining centers was founded. The founded model provides a theoretical basis of assessing reliability characterizations and adopting reliabil- ity growth technical measures for machining centers. |
