In this study, a method of micro-electrochemical slab milling with disc electrode is proposed for fabricating micro-groove structures on the surface of the workpiece. The disc electrode is in-situ prepared by micro-WEDM and subsequently used for micro-electrochemical slab milling process. The effects of the main electrochemical parameters, such as electrode feed rate of disc electrode and pulse width of power generator, on the width of the micro grooves and surface quality on 304 stainless steel were discussed. Finally, a micro-groove with a groove width of 254μm and good surface quality has successfully processed using the disc tool electrode with edge width of 170μm and proper process parameters. The proposed method broadens the machining flexibility and capability of micro electrochemical machining technology.
