Abstract

Electrochemical discharge machining (ECDM) is the hybrid machining process combination of electrodischarge machining and electrochemical machining process. ECDM is different machining process for micro-drilling and micro-grooving of variety of glasses, ceramics and composites. Electrochemical discharge machining also called as spark assisted chemical engraving (SACE). ECDM process is an effective and micro-machining process for non-conductive materials. It is used in micro-electromechanical system (MEMS) applications. ECDM parameters are material removing rate (MRR), surface finish, tool wear rate (TWR), voltage, concentration, current in the drilling process. ECDM process can apply only micro-machining for non-conductive materials. A setup is developed and maintaining stand of distance between tool and work piece.
