“…The influence of process parameters, such as voltage and current on varying thickness of different grades of steel material namely 1040, cold work tool steel (2379), and plastic mould steel (2738) was carried out. It is observed for same process parameter combination, different roughness values are obtained due to change in the material property [26][27][28]. The effect of process parameters, like pulse duration, pulse-off time, open circuit voltage, servo feed, servo voltage, dielectric flushing pressure, wire feed, and wire tension on surface roughness of Ti6Al4V material [29][30][31], AISI 4140 steel material [14], and AISI D2 tool steel material [32] were studied.…”
