Abstract:  During MQL cutting process, the atomization characteristics of the system affect the effect of mist particle penetration between interfaces.A laser particle size analyzer was used to test the atomization characteristics of the MQL system by a single factor test. The influences of system parameters such as air flow rate, injection distance, cutting fluid dosage and cutting fluid type on the average diameter and particle size distribution of fog particles were analyzed. Results show that air flow and spray distance are main influencing factors. When the air flow is maintained in 80~90 L/min and the spray distance is controlled in 40~50 mm, the atomization effect may be better. Based on aetor analysis method, a mist particle diameter prediction model was established under the condition of MQL. The error is less than 10%. It shows a good performance in describing the influence of MQL system parameters on atomization characteristics.

Key words: minimum quantity lubrication(MQL), atomization characteristic, mist particle size distribution, actor analysis method

摘要: 微量润滑切削过程中,系统的雾化特性会影响界面间的雾粒渗透效果。采用激光粒度分析仪对微量润滑系统的雾化特性进行了单因素试验测试,研究了空气流量、喷射距离、切削液用量以及切削液类型等系统参数对雾粒平均直径及其尺寸分布的影响。结果表明,空气流量、喷射距离为主要影响因素,当空气流量保持在80~90 L/min、喷射距离控制在40~50 mm范围内时能够获得较好的雾化效果。基于因次分析法建立了微量润滑条件下的雾粒直径预测模型,其误差小于10%,能够较好地描述微量润滑系统参数对雾化特性的影响。
