摘要
目前我国数控机床及其关键功能部件的可靠性水平与国外差距明显。而可靠性已经成为衡量数控机床及其关键功能部件性能好坏的重要指标之一,因此,数控机床及其关键功能部件可靠性研究迫在眉睫。文章在国内外大量相关可靠性研究的基础上,归纳总结了数控机床可靠性故障数据的分析及处理方法、可靠性评价方法、可靠性增长技术及可靠性试验技术;分析了数控机床关键功能部件可靠性研究与整机可靠性研究的不同之处,提出了数控机床整机及关键功能部件可靠性研究方案及展望。
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.
