In this project, a novel electroosmosis mechanism of cutting fluids in machining interface capillaries is revealed and investigated to improve fluid penetrability, as well as enhance its lubrication and cooling effects during manufacturing processes. The increase of the capillary electroosmosis of cutting fluids at tool-chip interface leads to a significant improvement in the surface quality and tool life. This research project will first systematically understand the characteristics of tribo-potential/electron emission of friction fairs during friction processes. The formation mechanisms of tribo-electrostatic field and its effect on the fluid capillary electroosmosis on the rubbing interface will then be investigated. Based on tribological characterization and numerical analysis, the capillary electroosmosis mechanism of cutting fluids at the frictional interface will be revealed. Secondly, the project will establish a theoretical model of fluid penetration under capillary electroosmosis condition by systematically investigating the formation mechanism of capillary electroosmosis and its penetration process at the tool-chip interface. The role of capillary electroosmosis in improving fluid capillary penetration will be investigated by use of the developed model. Finally, the formula schemes of cutting fluids for improvement in the capillary electroosmosis will be investigated. The effect of fluid capillary electroosmosis on cutting processing characteristics including cutting forces, cutting temperatures, tool wear and surface integrity will be systematically compared and optimized under different cutting parameter conditions. Through the research of this project, a novel capillary electroosmosis machining technology will be achieved.
