针对封闭深窄盲槽结构的加工难点,提出了一种管电极电解铣削加工工艺。通过仿真软件对电解铣削过程中的流场进行建模仿真,利用高速摄影仪观测流场分析该方法的可行性。采用外径0.8 mm的管电极在不锈钢上进行电解铣削加工深窄槽试验,研究电解液压强对深窄槽轮廓精度的影响规律,成功加工出槽宽(1±0.05) mm、槽深(2.5±0.05) mm的高精度、侧壁陡直的封闭深窄盲槽。
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.
