EFFECT OF FLUSHING CONDITIONS ON MATERIAL REMOVAL RATE IN EDM
Keywords:
Electric Discharge Machining (EDM), Material Removal Rate, Ton, Duty Cycle, Flushing ConditionAbstract
This paper is focused on the comparative study of process control variables on Material removal rate under side and centre flushing conditions in EDM. In this research, one variable at a time methodology is adopted to investigate the effect of six control variables namely current, voltage, spark gap, Ton, duty cycle, and flushing pressure, on material removal rate (MRR) in Electrical Discharge machining (EDM). The experiments were conducted on round copper tools of EN 31 with kerosene as dielectric under center flushing & side flushing conditions. The results indicate that machining parameters and flushing conditions have significant effects on Material Removal Rate (MRR).
