| Abstract: | Based on the failure data of a computer numerical control (CNC) system in one and a half year, the failure positions and failure causes of the CNC system were analyzed. The frequent failure position, feed servodrive unit, was investigated in detail. It is found that the main failure cause of CNC system is breakage of components and the reliability design for the feed driving control board should be done.The corresponding improvement measures are put forward to provide a basis for the reliability design and analysis of CNC system. |
