STUDY OF THE EFFECT OF MACHINING PARAMETERS ON MATERIAL REMOVAL RATE AND ELECTRODE WEAR DURING ELECTRIC DISCHARGE MACHINING OF MILD STEEL

摘要

Electric Discharge Machining (EDM) is one of the most popular non-conventional machining processes. During Electric Discharge Machining (EDM) the process parameters plays a very important role in deciding the material removal rate (MRR) and electrode wear (EW). In the present investigation mild steel specimens have been machined by using Electric Discharge Machining (EDM). The material removal rate (MRR) and electrode wear (EW), thus, measured have been correlated with the machining parameters such as, spark current, pulse on time and pulse off time by the use of response surface methodology (RSM). The equations, thus, derived have been used to find out the effect of machining parameters on the material removal rate (MRR) and electrode wear (EW) during Electric Discharge Machining (EDM) process.
