摘　　要：发现了ＰＣＤ刀具切削时出现的用较高表面粗糙度的刀具可以加工出较低表面粗糙度的工作这一与传统切削理论相反的超越性加工现象，并对这一现象的判别标准进行了研究。The outstripping phenomenon that the workpiece with low surface roughness is obtained by the PCDcutter with high surface roughness, is discovered in this paper, which is contrary to the traditional cuttingtheory. And the judging standard of outstripping phenomenon is also discussed.

关 键 词：PCD刀具 超越性加工 表面粗糙度 判别标准
