In recent years, ceramics for a few mechanical and electronic parts are performed on the cutting process of the green-compact. The residual crack on the finished surface is influenced the strength of the ceramics after the sintering. The purpose of this paper is to clarify the cutting performance of the ceramics green compact that used the alumina of the grain size 0.2 μ m. The machining performance of alumina green-compact is discussed from view point of the relation between the shape of tool edge and the surface roughness on the workpiece. In the cutting test by turning, the cutting condition is cutting speed 100m/min, feed 0.1mm/rev, depth of cut 0.2mm. The tool shape on the insert tip are made chamfer angle from -25°to 5° The main results obtained are follows:(1) The surface roughness in feed direction and the in circumference direction was existed an correlative. (2)In the chamfer angle -10°on the tool edge, the surface roughness at cutting could give rise to Rmax 4.0 μm. (3)The tool life of this cutting was lager than other cutting.
