| Abstract: | 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. |
