To expand the application of fine ceramics to machine parts, a proper machining method is indispensable, which can satisfy severe demands for dimensional accuracy, geometrical accracy and surface integrity of ceramics parts in the same manner as machining of metal. Then the processes of deformation and fracture of fine ceramics, which is very hard and brittle, must be clarified to establish an available machining method. This report made clear the processes of deformation and fracture of fine ceramics in a transitional cutting. Experiments were carried out under conditions in which fine ceramics was cut at very small depth of cut using sintered diamond tools. The experiments give evidence that cutting process of fine ceramics are characterized by remarkable phenomena such as rubbing, indenting; swell-up and crack initiation, large-scale fracture, and that these phenomena occur corresponding to interference depth of cutting edge. Also some factors influencing these phenomena are discussed.
