Research on the ELID-ultrasound dressing technology based on multi-field coupling theory

摘要

This paper utilizes the multi-field coupling theory to conduct numerical simulation for the electrolyte flow state between the anode and cathode of ELID (Electrolytic In-process Dressing) - ultrasound dressing system. The simulation results show that this theory is an effective solution to the electrolyte's uneven distribution problem of traditional ELID dressing, thereby the uniform electrolysis on the grinding wheel surface enabling the oxide film to cover the entire surface. In addition, as the local vibration of the electrolyte caused by the ultrasonic vibration is conductive for the updating of ion concentration reacting around the electrolyte as well as the acceleration of the process of the electrode reaction. This method is suitable for ultra-precision grinding as well as the high-speed and efficient grinding.
