采用TiC/TiCN/TiN三层涂层硬质合金刀具对0.45%碳钢进行了高速刻槽试验，评价了微量润滑在高速切削加工中的性能。在4m/h和5m/h的高速切削液中，以7ml/h的小流量恒定供给植物油的MQL较溶液切削液更有效地降低了角部和后刀面的磨损，在MQL沟槽中，随着供气压力的增加，磨损量急剧减少。这表明，送风对油雾向后刀面磨损区和已加工表面界面的输送起着重要作用。在此基础上，设计了一种可控油雾方向(COD)工具，并证明了该工具在减少供油量的情况下具有很高的性能。
The performance of minimum quantity lubrication (MQL) in high-speed cutting was evaluated in grooving 0.45%C carbon steel with a carbide tool coated with TiC/TiCN/TiN triple coating layers. MQL with supplying vegetable oil at a small and constant rate of 7ml/h reduced the corner and flank wears more effectively than a solution type of cutting fluid at high cutting speeds of 4 and 5m/s. In MQL grooving, the wears decreased drastically with increasing the pressure of air supply. This suggested that the air supply took an important role in transporting the oil mist to the interface between the flank wear land and machined surface. Then, a controlled oil mist direction (COD) tool was devised and its performance was proved to be high at a reduced rate of oil supply.
