超精密自由曲面栅格铣削是一个非常复杂的加工过程，对小零件的加工时间较长。因此，在超精密栅格铣削加工中，金刚石刀具的磨损不仅是提高加工成本的关键因素，也是制约其加工性能的重要因素。本文研究了在有润滑和无润滑两种加工环境下，单晶金刚石刀具在铜光栅磨削过程中的过程监测和磨损评估方法。实验结果表明，冲击和自由振动是光栅式铣削加工过程中的重要动态特性，导致刀具刃口产生明显的微屑磨损。
Ultraprecision freeform raster milling is a very complex machining process, and long machining time is used for small components. Therefore, the diamond tool wear is a crucial factor that not only raises the machining cost but also limits the cutting performance in ultraprecision raster milling. In this paper, the methods of process monitoring and wear evaluating of single-crystal diamond tools during the raster milling of copper are studied in two types of cutting environment: with lubrication and without lubrication. Experimental results indicate that the impact and free vibration are important dynamic characteristics in raster milling process that result in the obvious microchipping wear on the cutting edge.
