Abstract: Aiming that CNC machine maintenance personnel often meet stochastic malfunction, and repair work often can not be done, it was analyzed that what was causing trouble fault and the randomness of the two reasons. Combined with typical examples and the equipment fault， five kinds of based on this kind of fault detection and diagnosis methods were introduced. It was key explained in mastery of CNC machine logic diagram, timing diagram and the trees case, establishing the correct maintenance ideas, how to find fault. At the same time the notes were explained that should pay attention to when maintenance safety matters. The results indicate that the methods presented is easy to grasp and operate. These methods to maintenance personnel work has certain significance, it is a systematic summary to randomness fault.
Key words: computer numerical control(CNC); randomness faults; detection diagnosis method
