| Abstract: | In order to solve the machining difficulty of deep-narrow structure,a method of electrochemical milling with tube electrode is proposed.The simulation of the flow field of electrochemical milling was established and simulated by simulation software,and the feasibility of the method was analyzed by observing the flow field with a high-speed camera.A tube electrode with an outer diameter of 0.8 mm was used to perform a deep-narrow groove test on stainless steel,and the influence of the electrolyte pressure on the accuracy of deep-narrow grooves was analyzed.Finally,a deep-narrow groove with width of(1±0.05)mm and depth of(2.5±0.05)mm was fabricated with high precision and steep sidewall by the method. |
