Effect of Various Parameters on Machining of EN-31 in Wire Electrical Discharge Machining

With the increase in research activities in nuclear, automobile, aerospace industries and medical industries the need for micro machining process is also arising. Non-conventional machining with hybrid arrangement is more efficient as compared to the Conventional machining on the count of maximum material removal. Wire Electrical Chemical Discharge Machining (WEDM) is one of the best machining used for machining conductive as well as non-conductive material using the effect of electro discharge machining process. In this paper effect of various parameters of WECDM process on material removal of EN-31 is studied. The effect of spark/pulse on time, pulse off timer, peak current and wire feed showed significant effect on material removal.
