摘　　要：采用了微量润滑技术的钻削在长距或小孔径的条件下有必要对所供给的油雾和压缩空气进行最佳化分析。本文首先对切削变形与切削热分布的总能量进行了分析,并在把普通钻削过程中油雾假设为稳态可压缩绝热紊流状态的假设条件下,通过分析得到油膜厚度、气流速度、压缩空气温度和刀具平均温度等重要影响参数的相互关系。最后,给出微量润滑钻削条件下,切削过程中所需的油膜和压缩空气的最佳容量。It is necessary to optimize the supply of oil mist and compressed air in the drilling case of long distance or small diameter using MQL （ Minimal Quantity of Lubrication） method. The total energy for deformation process and distributions of cutting heat were analyzed. Based on the hypothesis that oil mist is in a steady-state compressible adiabatic turbulent flow under the ordinary MQL cutting conditions, the relationships of main parameters were obtained through the analysis of the calculation software, such as the thickness of oil mist, the flow speed, the temperature of the compressed air and the average temperature of tool. The optimal volumes of oil mist and compressed air of MQL in drilling were presented for the cutting process.
