摘　　要：TC4(Ti-6Al-4V)合金作为一种典型的难加工材料,过快的刀具磨损严重制约了其切削加工效率。本文提出了一种充气加压式固体内润滑刀具,并采用ABAQUS软件对其切削TC4合金的加工性能进行了有限元分析。结果表明,该刀具利用充气压力将固体润滑剂直接输送到刀具刃部,可在不使用冷却液的情况下达到冷却润滑切削加工区,降低自润滑车刀—TC4合金的摩擦系数的目的,对降低切削温度具有明显效果。As a kind of typical difficult -to -machine materials, TC4 （Ti -6Al -4V） alloy was restricted in its cut- ting efficiency because of the tool wear too fast. A kind of solid internal lubrication tool in inflation pressure style was intro- duced, and its cutting performance was investigated by finite element analysis with ABAQUS software. The results showed that an obvious effect in decreasing the cutting temperature can be obtained by reducing the friction coefficient between the self - lubricating tool and the TC4 alloy through delivering the solid lubricant directly to the blade of the cutting tool without the use of coolant conditions.
