Micro-Electrical Discharge Machining SpringerLink
4.6.5.2 Micro-Wire Electro-Discharge Grinding. Micro-wire electro-discharge grinding (micro-WEDG) is a micro-fabrication process that uses electrical discharges in a dielectric fluid to erode material from conductive workpieces and produce micro-shafts. The discharges occur across a small gap (~2 μm) filled with dielectric oil.6. MRR • Material is mainly removed by ECD, while the MA of the abrasive grits accounts for an additional 5 to 10 percent of the total material removal. • Removal rates by ECG are 4 times faster than Electrochemical grinding (ecg) PPT SlideShare

ELECTRO CHEMICAL DISCHARGE MACHINING: PROCESS CAPABILITIES
Electrochemical discharge machining (ECDM) is a promising hybrid process for high-performance machining of non-conductive glass. ECDM drilling has been found to have different characteristics andtime to machine metals and diamonds with electrical discharges. However, work on electrical discharge machining was carried out in 1943 during World War-II by two Russian scientists, Dr.Boris Lazarenko and Dr.Natalya Lazarenko at the Moscow University History They developed a controlled process of machining difficult-to-machine metals by Electric Discharge Machining (EDM) PDF Machining

Optimization of EDM Process Parameters: A Review of Springer
Abstract. Electric discharge machining (EDM) is a vital non-traditional process, which is extensively used for machining a range of difficult-to-machine material such as heat-treated tool steels, composites, ceramics, carbides, heat-resisting steels with convoluted shape. The various process of EDM: die sinking EDM, wire EDM (WEDM), Micro EDM process is one of the micro- machining processes. It can be used to machine micro features and makes a micro parts. There is a huge demand in the production of microstructures by a non-traditional method which known as Micro-EDM. Micro-EDM process is based on the thermoelectric energy between the workpiece and Review Study and Importance of Micro Electric Discharge Machining
