a BUE forms near the cutting edge, the relative velocity of chip leads to squeezing the attached particles that are enclosed between tool rake face and underneath of the chip surface. Due to severe... ARTICLE J. Cent. South Univ. (2019) 26: 1050-1064 DOI: https://doi.org/10.1007/s11771-019-4070-2 Effects of reinforced nanofluid with nanoparticles on cutting tool wear morphology Seyed Hasan......
,AlTiN-Cu 涂层刀具的切削寿命比AlTiN 涂层刀具的低,这是由于在湿式切削不锈钢时金属铜的润滑效果不明显,同时,Cu 的加入降低了涂层的硬度,致使涂层切削寿命下降. 图6 干式切削后刀面平均磨损量随时间的变化曲线 Fig. 6 Changing curves of average flank wear with time during dry cutting 图7 涂层刀具在干式切削7 min后刀面的磨损形貌 Fig. 7 Micrographs of flank wear region of coating tool after dry cutting for 7 min 图8 湿式切削后刀面最大磨损量随时间的变化曲线 Fig. 8 Changing curves of maximum flank......
