Abstract: The concept of electrochemical discharge machining (ECDM), also known as electrochemical spark machining (ECSM), was presented for the first time in 1968. Since then, this technology remains a research topic. In the domain of non-conventional machining methods, the electrochemical discharge machining (ECDM) process is emerging as a potential contender for machining of nonconductive, hard, and brittle materials. In the general ECDM process, the gas film forms, and electrical discharge appears at the tool end that is exposed to the electrolyte. In this research work, the ECDM experimental setup was fabricated for machining non-conducting materials. This machining process was used for the machining of silicon carbide which is very brittle and hard in nature. The input parameters considered for the process were selected as voltage, electrolyte concentration, inter-electrode gap whereas MRR, tool surface geography, and heat-affected zone were obtained as response parameters.
