摘要
利用工业电视摄像系统对冰洲石的切削过程进行观察和记录。分析指出冰洲石的切削过程为脆性破裂过程。工件已加工表面通过2种形式的破裂而形成：沿解理面光滑平整的大块破裂；晶粒断裂引起的层状小块破裂。还研究了已加工表面下破坏区的特征。进一步指出，当切削方向背离破坏区扩展方向时，能得到较好的已加工表面质量。
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.
