a b s t r a c tIn the present study, the temperature distribution on the surface of workpiece and tool during a single discharge in the electrical discharge machining process has been simulated using ABAQUS code finite element software. The temperature dependency of material properties and the expanding of plasma channel radius with time have been employed in the simulation stage. The profile of temperature distribution has been utilized to calculate the dimensions of discharge crater. Based on the results of FEM and the experimental observations, a numerical analysis has been developed assessing the contribution of input-parameters on the efficiency of plasma channel in removing the molten material from molten puddles on the surfaces of workpiece and tool at the end of each discharge. The results show that the increase in the pulse current and pulse on-time have converse effects on the plasma flushing efficiency, as it increases by the prior one and decreases by the latter one. Later, the introduced formulas for plasma flushing efficiency based on regression model were utilized to predict the cardinal parameter of recast layer thickness on the electrodes which demands expensive empirical tests to be obtained.

“…It has been proved that the crater volume obtained by using the Eq. (7) is equal to the volume by the assumption of a circular parabolic geometry for the crater [19] since the parabolic counter fits the isothermal counter passing through the (x i ,z i ) coordinates. This geometry is shown in Fig.…”

“…Many attempts have been made on the evolution of the plasma channel radius. The empirical equations have been presented to calculate the plasma channel radius [8][9]. Compared to other approaches, the equivalent heat input radius based on experimental data has been proposed by Ikai [9], which is closer to the actual EDM process.…”
