A Review Paper on Electro Chemical Discharge Machining Technique
Rajeev Sharma
Abstract: Electrochemical Micro Machining (ECMM) and Electric Discharge Micro Machining (EDMM) processes have high potential when applied in micro regime for good accuracy and shape reproduction. But they have a limitation that only electrically conducting materials can be machined by them. To overcome this limitation, a combination of ECMM and EDMM processes has been conceived, and it is known as “electrochemical spark micro machining” (ECSMM) / “electro chemical discharge machining” (ECDM). Electro Chemical Discharge Machining (ECDM) is a controlled metal-removal process which is used to remove the metal by means of electric spark erosion. In this process an electric spark is used as the cutting tool to cut (erode) the work piece to produce the finished part to the desired shape. There are various ECDM process parameters (variables) on which the machining performances depends such as these parameters are polarity, peak current, pulse on time, pulse off time, flushing pressure, Voltage and Concentration. This paper reviews the vast array of research work carried out within past decades for the development of ECDM.
Keywords: Electrical Chemical discharge machining, ECDM parameters, machining characteristic
