There are great differences in ground surface integrity and residual stress between CBN and diamond wheels. In our single-grit cutting, the measured cutting forces with CBN and diamond grains were largely different. For further understanding of the difference, friction behavior in cutting is most important characteristic to be solved. So, orthogonal cutting test has been performed to measure friction angle on a carbon steel with CBN, diamond compax, and grain tools. And, the cutting test in SEM was also performed to observe chip formation. There are no differences between friction angles of CBN and diamond tools in ordinary cutting test. However, there is great difference in slow and short distance cutting test. Diamond tools showed significantly small friction angle at about first cutting of 1mm. In the cutting in SEM, the diamond compax and grain tool show a large shear angle and flow type chip, while CBN compax and grain tool show small shear angle with shear type chip. Therefore, diamond tool keeps a small friction coefficient during short cutting distance, and the phenomenon was shown in high speed single grit cutting test.
