摘要
在亚微米级CNC超精密车床上进行了单晶金刚石刀具切削试验 ,根据试验结果分析了切屑形成机理和最小切削厚度与表面粗糙度之间的关系 ,建立了加工表面微观形貌的几何模型。研究结果表明 :通过计算最小切削厚度值可预测金刚石车削加工可获得的表面粗糙度值。
The cutting tests with single crystal diamond tools are carried out on a submicron CNC ultraprecise lathe. According to test results, the chip formation mechanism and the relationship between the minimum cutting thickness and surface roughness are analyzed, and the model of micro topography on the machined surface is established. The investigation shows that it is possible to predict the surface roughness obtained in the diamond turning by calculating the minimum cutting thickness.
