摘　　要：近年来,数控机床因素导致零件发生质量问题的案例在生产实践中屡见不鲜,但对于这些问题却缺乏可靠的分析方法。通过对数控机床的特性进行研究,总结出对产品质量影响最大的几个方面,对解决因机床原因引起产品质量问题的分析方法进行了探讨,并成功应用于工程实践中。Parts failure of CNC machining which is caused by machine tools factors are commonly observed in recent years, but reliable methodologies that could solve these problems are highly lacked. The main factors that have great impact on machining quality is summarize based on analysis of characteristics of CNC machine tools. The procedure to solve machining problems from the perspectives of machine tools characteristics is discussed. Two case studies from industry, which is caused by static and dynamic characteristic of machine tools, is discussed as well.
