摘　　要：对超精密加工表面的划伤机理进行了系统的分析,并将其划伤过程概括为四种状态:摩擦、镶嵌、划沟、脱落。通过对影响表面划伤各种影响因素的详细分析,提出了避免表面划伤的控制方法。This paper systematically analyzes seratehing mechanism for ultra-precision machining surface,and the process includes four stages such as friction, inlaying, scratching and abscission. It puts forward some control methods to avoid surface scratching through analyzing various factors.
