Abstract

The characteristics of performance degradation data are analyzed. The disciplinarians of numerical control machine tool performance degradation data with time are analyzed, the reliability assessment methods with performance degradation data based on performance degradation distribution is presented. The performance gradation data contain abundant numerical control machine tool reliability information, the reliability and lifetime of numerical control machine tool can be evaluated with performance degradation data availably, even if the failure time cannot be obtained by life testing.
