In order to solve the problem of poor localization of electrochemical machining(ECM),a coaxial megasonic assisted jet ECM method was proposed.Theoretical analysis and experimental research were conducted on the jet ECM process of 304 stainless steel using this method.The analysis result indicated that megasonic assistance cannot only enhance the electrolyte flow rate and continuously update the electrolyte in the anode processing area,but also promote the discharge of reactive gases and thereby improve the accuracy and efficiency of ECM.The research result showed that when the fixed electrolyte flow rate is 0.9 L/min and the electrolysis voltage is 50 V,the depth to diameter ratio of the electrolytic circular pit under 22 W megasound power is 0.173,which is 12.34%higher than that under no megasonic assisted.Meanwhile,the depth to width ratio of the pit etching is further improved,verifying the effectiveness of megasonic assisted jet ECM method.
