Circular cutting with a single point diamond cutting edge, in which the depth of cut is very small but reaches a maximum at one point, has been carried out in order to investigate the cutting of sialon and/or partially stabilized zirconia under conditions similar to grinding. This has been carried out by investigating the sliding phenomenon of a diamond cutting edge, the normal cutting force, groove profile, stock removal and so on. It has become clear that there are three different regions within the cut: elastic, plastic and cutting regions are all present when there is interference between a diamond grain and a fine ceramic. A cutting groove is generated by plastic deformation as well as brittle fracture.
