In order to perfect traditional electrochemical jet machining and improve the machining quality

a wire-preposed electrochemical jet machining(WPEJM) technology is proposed

in which a flexible electrode wire is fixed in the high-speed jet to concentrate the electric field and improve the localization of jet electrolysis. According to the processing principle of this technology

software COMSOL is used to conduct simulation analysis on the distribution of multiple physical fields in machining process

and an experimental platform is set up to verify its feasibility. The preliminary results show that under the same condition

compared with the traditional electrochemical jet machining

the proposed method increases the machining efficiency and the depth-diameter ratio of the pit. Furthermore

the inner surface quality of the pit is significantly improved.
