This chapter provides a comprehensive overview on the micro-electrical discharge machining (micro-EDM) process. Micro electrical discharge machining is similar with the principals of electrical discharge machining (EDM), a thermal process that uses electrical discharges to erode electrically conductive materials. (Electrical Discharge Machining) involves the removal of metal from a workpiece by sending an electric current through an electrode or wire.

Developed in the mid 1970s In the mid 1980s, the EDM techniques were transferred to a machine tool Today,it is a viable technique that helped shape the metal working industry. The physical principle of micro-EDM and differences between macro- and micro-EDM and micro-EDM system components are discussed. Micro electrical discharge machining (μEDM) is an atmospheric-pressure plasma-assisted technology that uses point-to-plane discharges in liquid dielectrics to remove microscopic quantities of electrically conductive materials. Yi SM, Lee YS, Chu CN (2006) Straight hole micro EDM with a cylindrical tool using a variable capacitance method accompanied by ultrasonic vibration. The principle is the same for wire erosion, die-sinking and micro-drilling. The thickness of recast layers produced during electrical discharge machining (EDM) is an important process performance measure as it may indicate an extent of crack propagation in a machined surface or thickness of a functional layer alloyed onto a machined surface.

Electrical discharge machining promises high-quality, lower-cost substrates, Rakwal D, and Bamberg E, Compound Semiconductor, March 2009, pp 17-18 (2009) Orbital electrode actuation to improve efficiency of drilling micro holes by micro-EDM , Bamberg E, and Heamawatanachai S, Journal of Materials Processing Technology 209(4), pp 1826-1834 (2009).. Electrical Discharge Machining (EDM) Electrical Discharge Machining (EDM) is ideal for intricate burr-free cutting of intricate contours or cavities in hard materials, eliminating the need to soften the material before machining, and then re-harden it through heat-treating. The melting process, triggered by discharging electricity from the piece's surface, makes it … Micro Microform Corporation electrical discharge machining provides wire edm machining, sinker & small hole EDM drilling, job shop, including milling & turning. Reverse micro-electrical discharge machining (R-MEDM) process has a capability to fabricate such arrayed features on a variety of workpiece materials irrespective of their mechanical properties. WIRE ELECTRICAL DISCHARGE MACHINING. Electrical discharge machining operates independently of the mechanical properties of the materials to be machined and is almost free of process related forces, enabling structures with very small dimensions to be produced. However, there has been lack of systematic efforts to evaluate how dielectric conductivity affects the micro-electrical discharge machining (micro-EDM) process, in particular.
