摘　　要：通过温度采集、力学性能检测和组织形貌分析,系统研究了微量润滑切削TC4钛合金时不同润滑油用量对冷却效果、切削性能和组织性能的影响规律。试验结果表明:同一切削条件下,润滑油用量Q在一定范围内值越大,冷却效果、切削性能越佳,加工后材料显微组织尺寸越小,显微硬度越大;当Q取值35-40ml/h时,各性能趋于最优。然而,Q超过40ml/h后,冷却效果、切削性能和工件的组织性能反而降低。The influence of the cooling effect,cutting and microstructure performance when the lubricating oil was changed when cutting TC4 titanium of MQL was studied by analyzing temperature acquisition,the mechanics performance testing and the morphology analysis. The results show that,under the same machining conditions,the larger amount of lubricating oil（ Q） within a certain range,the better effect of cooling and cutting. The smaller size of the material microstructure and the greater micro- hardness will be after processing. When the Q value was 35- 40 ml / h,all the properties are approaching optimal statue while all the properties would reduce when the flow rate exceeds 40 ml / h.
