Abstract

In order to improve the stability and localization of narrow-slit electrochemical machining,a cathodic com- pound feeding mode with continuous linear feeding and vibration was proposed,and the corresponding machining experi- ments were carried out on the basis of the improved waveform-adjustable vibration system with a vibration frequency of 0 ～50Hz and with a vibration amplitude of 0 ～2mm.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 0.305mm can be machined out by adopting the cathodic compound feeding mode.

Key words： electrochemical machining; compound feeding; narrow slit; machining localization
