Powder mixed electric discharge machining(PMEDM)is one of the modern developments in electric discharge machining(EDM)*** the present work,finite element modeling has been carried out considering randomly oriented multiple sparks during *** thermal analysis is done to obtain temperature distribution,volume removal,and proportion of volume removed by melting and evaporation at different current,pulse on time and fraction of heat that enters to work *** growing spark behavior and Gaussian distribution of heat source is used to simulate multiple *** distribution along radial direction shows peak temperature at center of spark and thereafter a gradual decrease with increase in radial *** depth direction temperature sharply decreases that forms wider craters with shallow depth in *** temperature and volume removal increases with current more *** removal by melting is much higher than evaporation at lower current settings and with higher current almost equal amount of material is removed by melting and evaporation thus reducing the re-solidification of melted *** plays a significant role behind the contribution of material removal by evaporation followed by fraction of *** in pulse on duration increases the total volume of material removal however does not significantly increase the proportion of volume removal by vaporization.
