摘要： 使用未涂层的和AlCrSiN涂层的硬质合金车刀片以3种切削速度干式车削Ti-6Al-4V钛合金。研究发现AlCrSiN涂层刀片的切削寿命在各切削速度下都超过无涂层刀片, 而切削力、切削温度和工件表面粗糙度3项指标均低于无涂层刀具, 说明AlCrSiN涂层能够有效地保护基体从而维持刀具的锋利度。2种刀具在切削过程中均出现切削力先上升后下降的现象, 这与二者高温下产生的润滑氧化物有关。切削温度和工件粗糙度都与后刀面磨损量有正相关关系, 即随着后刀面磨损量的增加, 温度和粗糙度都随之增加, 但温度的增加还与前刀面第一变形区塑性变形增大, 热量增加有关。另外, 2种刀具产生的切屑尺寸、颜色、锯齿频率也证明了AlCrSiN涂层刀具磨损较慢，切削温度较低。

Abstract: Ti-6Al-4V titanium alloy was dry turned by uncoated and AlCrSiN coated carbide inserts at three cutting speeds. It was found that the cutting life of AlCrSiN coated inserts exceeds uncoated inserts at all three cutting speeds and meanwhile the three values of cutting force, cutting temperature and workpiece surface roughness are lower than that of uncoated tools, which shows that AlCrSiN coating can effectively protect the substrate and maintain the sharpness of the tool. During the cutting process, the cutting force of both tools increased first and then decreased, which is related to the lubricating oxides produced by the two tools at high temperatures. Both cutting temperature and workpiece roughness have a positive correlation with the wear of the flank, that is, as the wear of the flank increases, the temperature and roughness increase accordingly, and incidentally, the increase in temperature is also related to the increase in plastic deformation and heat in the first deformation zone of the rake face. In addition, the chip size, color, and sawtooth frequency produced by the two tools also prove that the AlCrSiN coated tool has lower wear rate and cutting temperature than the uncoated tool.

Key words: AlCrSiN coating, Ti-6Al-4V, cutting force, cutting temperature, roughness, tool wear
