Micro-electrical discharge machining

Abstract

This chapter provides a comprehensive overview on the micro-electrical discharge machining (micro-EDM) process. The physical principle of micro-EDM and differences between macro- and micro-EDM and micro-EDM system components are discussed. A discussion on major operating parameters of micro-EDM and their effect on the performance parameters is presented. A brief discussion on variants of micro-EDM and their industrial applications has been included. The research advances on the areas of micro-EDM and micro-EDM-based compound and hybrid machining processes have been discussed. Finally, a comparative evaluation of micro-EDM to other machining processes has been presented.
