摘要：
In order to improve the stability and localization of narrow-slit electrochemical machining, a cathodic compound feeding mode with continuous linear feeding and vibration was proposed, and the corresponding machining experiments were carried out on the basis of the improved waveform-adjustable vibration system with a vibration frequency of 0~50 Hz and with a vibration amplitude of 0~2 mm. The results show that, (1) in comparison with linear feeding, cathodic compound feeding is more effective in improving machining localization and reducing narrow slit's width; (2) high vibration frequency and amplitude both help reduce the stray corrosion and improve the narrow-slit machining consistency; and (3) different shapes of narrow slits with a slit width of 0.305 mm can be machined out by adopting the cathodic compound feeding mode. © 2016, Editorial Department, Journal of South China University of Technology.
