| Abstract: | To alter the status quo that the failure rate of the Chinese-built computer numerical control(CNC) machine tools is higher than that of the CNC machine tools produced by developed countries,their tracking tests on the spot and fault mode analyses were performed.The comparison of the fault modes shows that the former is different from the latter evidently in fault modes;the main factors causing the difference are found to provide an effective method for improving reliability of the former. |
