摘　　要：微量润滑(MQL,Minimum Quantity Lubrication)加工作为绿色切削技术,其应用逐渐广泛。相对于外置式MQL,内置式MQL具有渗透性好、切屑影响小、效率高等特点。为了寻求出内置式MQL的喷射特性对加工的影响规律,开发了车削内置式MQL系统,设计了四因素三水平的正交实验。以切削力和表面粗糙度为评价指标,切削液流量、空气流量、可生物降解润滑油及切削速度为变量,沿后刀面喷射,进行了车削GCr15轴承钢的正交实验,分析了喷射参数对加工的影响规律,并得到了优化的喷射参数,对机械加工工程应用具有参考意义。As a green cutting technology,Minimum Quantity Lubrication（ MQL） machining process is used gradually widely in manufacturing industry. Compared with the external MQL system,the built-in MQL system has the characteristics of good permeability,little influences of chip,high efficiency and so on. In order to analyze the influence law of the injection characteristic of the builtin MQL system on the machining process,the built-in MQL system was developed on turning,and the orthogonal experiment with four factors and three levels was designed. The cutting force and surface roughness were determined as the evaluation indexes,and the cutting fluid flow rate,the air flow rate,the bio-degradation lubricating oil and the cutting speed were selected as the variables in orthogonal experiment. The cutting fluids were sprayed along the flank to the tool tip in the high speed turning GCr15 bearing steel. Then the influence law of injection parameters on the machining process was analyzed. The optimized parameters are obtained,which have signifiant referance for engineering application in machinery machining.
