| Abstract: | An industrial television camera system is used to monitor and record the cutting process of iceland spar. It is pointed out that the cutting process of iceland spar is one in which the brittle fracture occurs continually. Machined surface of the workpiece is formed by cleaving along the cleavage planes of the crystal and intercrystalline fracture. Meanwhile characteristics of the damage zone under the machined surface are analyzed. It is further shown that the cutting direction has a remarkable effect on the machined surface quality. |
