Abstract:At present, the reliability of CNC machine tools and their key function units has a significant gap with that of abroad. The reliability has been an important index to judge the performance of CNC machine tools and their key function units. Therefore, the study on their reliability is extremely urgent. Based on the large quantities of reliability researches of home and abroad, the paper summarizes the anal ysis and processing method of the failure data, the reliability evaluation methodology, the reliability growth technology and the reliability testing technology of CNC machine tools. Additionally, the paper explains the difference between the reliability study of the key function units of CNC machine tools and the complete machines. Finally, the paper presents the reliability research scheme and prospect of CNC machine tools and their key function units.
