Study on Surface Finish of Carbon Steel by Ultra-Precision Diamond Cutting

This paper describes an influence of the cutting atmosphere and the carbon content on the surface roughness and tool wear in CO2-blow cutting of carbon steel with a diamond tool. The cutting tests were carried out by changing the cutting atmosphere and carbon contains in order to investigate the effect on the improvement of surface finish and the reduction of tool wear. The results indicated that the roughness on finished surface was improved by cutting in CO2 gas blow atmosphere and the tool wear increased with a decrease in the carbon content.
