摘要：In this article, the electrostatic atomization experimental setup was designed and fabricated, and high-speed camera was used to observe and analyze the atomization modes of graphite water-based and oil-based nanofluid using cutting tool as electrode under different electrode voltages and distances, flow rates, and nozzle angles. Three-dimensional finite element simulations of the electrostatic field between nozzle and cutting tool were conducted using the software Ansoft Maxwell to investigate the effect of electrode voltage and nozzle angle on the electrostatic atomization mode. The results indicate that spindle mode is a suitable electrostatic atomization mode for cooling and lubricating the cutting edge. The nozzle angle with the largest electrostatic field intensity is presented so as to generate good break-up effect of jet in spindle mode. Furthermore, the operating range of spindle mode in terms of the electrode voltage and flow rate for graphite water-based and graphite oil-based nanofluid under the nozzle angle with the largest electrostatic field intensity is achieved. The outcome of this study is helpful for further development of electrostatic atomization cutting technique.
