主 题：Oil mist Metalworking fluids Minimum quantity lubrication Flood cooling Turning
摘 要：The use of metalworking fluids during machining can generate oil mist and endanger the health of *** order to study the characteristics and emission laws of oil mist generated by machining,this study constructed a test bench to simulate the turning *** affecting the oil mist generated in the minimum quantity lubrication(MQL)mode and flood cooling mode were studied by means of single-factor experiments,and the formation mechanisms of oil mist were *** results show that the oil mist generated by the MQL system has two main sources,the initial escape of oil mist into the air and the evaporation/condensation of oil *** centrifugation has almost no effect on oil mist formation in the MQL *** mass concentration of oil mist generated by the MQL system is proportional to the cutting oil flow *** the work-piece is at room temperature,increasing the air supply pressure and nozzle distance,increases the oil mist mass *** the flood cooling mode,the concentration of centrifugal aerosol is linearly and positively correlated with the relative centrifugal force generated by the work-piece,and the coefficient of determination(R 2)is above *** oil mist mass concentrations in MQL mode is 8.33 mg/m^(3)~305.88 mg/m^(3).The MMD and SMD are 0.74μm to 4.42μm and 0.31μm to 2.14μm,*** oil mist mass concentrations in flood cooling mode is 0.2 mg/m^(3)~22.42 mg/m^(3).The MMD and SMD are 1.81μm to 6.58μm and 0.45μm to 5.13μm,respectively.
