Abstract

This research intents to gain the sight for the qualitative characteristics of precision cutting by using the CNC lathe with a mono-crystal diamond(MCD) tool having a straight cutting edge. As an absolute value of tool setting angle becomes smaller, the surface roughness has improved. We knew that according to each of the machine tools and cutting edge radius, there exist a proper mininum feed and depth of engagement for improving the surface roughness. This results suggest that the proper values of feed and depth of engagement are about 11-15 .mu. m/rev, 10 .mu. m, respectively.
