| Abstract: |
| Traditional metal cutting fluids have negative impact on environmental protection, human health and manufacturing costs and cannot meet the requirements of green manufacturing. Minimum quantity lubrication (MQL) is a green lubricant supply technology between flooding and dry processing. A small amount of degradable bio-lubricant is atomized by compressed air to form micro droplets, which plays the role of lubrication and wear resistance. However, there is no relevant research to summarize the law of precise transportation technology of atomized droplets, which fails to provide scientific guidance for minimum quantity lubrication supply parameters. For this purpose, the research progress on enabled atomization and transportation system of MQL was reviewed. The evolution law of droplet size and atomization angle of MQL two-phase flow pneumatic atomization with supply parameters was revealed. A new lubrication method of electrostatic enabled atomization MQL supply was proposed. The regulation mechanism of electrostatic enabled atomization performance and the permeation characteristics of charged fluid were analyzed. The homogenization mechanism of ultrasonic enabled atomized droplets and the optimization strategy of process parameters were expounded. Furthermore, the flow field distribution law of tool/grinding wheel-workpiece interface based on hydrodynamic model was analyzed, and the effect law of nozzle structure on droplet transportation was clarified, which provided theoretical support for the selection of nozzle placement parameters. Moreover, the research progress of the parameterized control device of the nozzle placement was discussed, and the problem of parameterized supply of the lubricating medium was solved. Finally, the key technologies of MQL compound synergism and intelligent supply were prospected in order to provide theoretical support and technical guidance for the engineering application of MQL technology. |
