Wire electrical discharge machining (WEDM) is a special form of traditional electrical discharge machining in which the electrode is a continuously moving conducting wire. The mechanism of metal removal in wire electrical discharge machining involves the complex erosion effect from electric sparks generated by a pulsating direct current power supply. The sparks generated between two closely spa...

Industries demand stringent requirements towards economical machining without hindering the surface quality while cutting high carbon chromium (HcHcr) steel. Electrical discharge (EDM) of HcHcr steel aims at reducing cost (i.e., maximize material removal rate (MRR) and minimize tool wear (TWR)) with good roughness (SR)). A comparative study was carried out on EDM D2 (DIN EN ISO 4957) by applyin...
