Improving surface integrity of electrical discharge machined ultra-fined grain Al-2017 by applying RC-type generator

“…47 In this process, the material removal mechanism is not performed by melting and vaporization of the surface layers; but mostly by electrostatic forces. 43,45 The electrostatic forces split and pull out the crystals of the material. Increasing the temperature of the surface layers results in slight decrease in the strength of the material and this helps the electrostatic forces to easily split the crystals.…”

The surface integrity of ultra-fine grain steel, Electrical discharge machined using Iso-pulse and resistance–capacitance-type generator

“…24 In this condition, the input heat is not adequate to melt the surface layers of the workpiece and the recast layer is not shaped (or shaped in very limited thickness) and the material removal mechanism is performed by electrostatic forces. 27–31 In RC-type generator, the tool is cathode and the workpiece is anode. Although the surface temperature of the workpiece is increased by hitting the electrons thrown from the anode, the temperature is not enough to melt the surface layers.…”

Thermo-mechanical analysis and optimal tension control of micro wire electrode

“…Jennes et al [3] developed an analytical model, which solves the one-dimensional heat flow equation and gets the stationary temperature distribution along the wire electrode. Analytical solutions may be difficult to obtain even for relatively simple geometries, so finite difference approach is widely used to obtain the temperature distribution profile for the wire, especially for transient problems [4][5][6]. Saha et al [7] also developed a simple finite element model by which the heat distribution can be mapped on the transient analysis of any point on the wire.…”
