ABSTRACT
EDM, or what is known as electric discharge machining (EDM), is one of the non-contact type machining processes that is performed at a very profound level of innovation, at the microscopic level, which in turn has evolved as a major part of the manufacturing industry. This process is a material removal method to achieve high accuracy in geometrical and dimensional parameters. The process has a principal phenomenon which has subjective based on thermal and electrical, which is concatenated as a thermoelectric phenomenon in which there is a gap created between the electrode and the workpiece, which in turn induces the desired output in the form of a material removal process from the surface. This chapter reviews the process of micro-EDM and its evolution in a surface modification that has upcoming technology-sustainable potential. The use of electrodes and their selection based on different materials is one of the most vigilant parts. Therefore one such electrode material, like the use of composite electrode Silicon (Si) and its use in the machining, is also covered as an intrinsic aspect.
