摘要：采用TiN涂层和未涂层M35高速钢丝锥进行高速切削试验，通过通用刀具寿命函数建立了丝锥寿命随切削速度变化的关系。结果表明，TiN涂层高速钢丝锥在较高的切削速度下攻丝加工40Cr-32HRC时可获得较长的切削寿命；根据通用刀具寿命函数模型论证了在一定切削条件下通过选择合适的切削速度范围，能使切削丝锥获得较长的切削寿命。

Abstract:Cutting performance tests are carried out with uncoated and TiN coated HSS cutting taps made of AISI M35.The cutting speed and tool life relations are established with the general tool life function.The results show that better tapping performance can be obtained with TiN coated HSS taps at higher cutting speeds when thread cutting 40Cr-32HRC.It is proved by the general tool life function that longer tapping tool life can be obtained at proper cutting speed range under certain tapping condition.
