Abstract:

Based on the statistical analysis of the failure data which were collected from some CNC lathes in the scene, it will establish the directed causality diagram of the internal subsystem and between subsystems. Considering the fault severity, frequency and the correlation coefficient between failure modes, it will obtain the failure related indicators of the subsystems. A critical subsystem that influences the reliability of NC lathe was presented, which provides the research direction for improving the reliability of NC lathe.

Key words: numerical control lathe, related failure analysis, directed causality diagram, failure related indicators
