Modeling and analysis of surface crack in EDMed AISI D2 steel

In this investigation, Response Surface Methodology (RSM) is used to explore the effect of four controllable input variables namely: discharge current (Ip), pulse duration (Ton), duty cycle (Tau) and discharge voltage (V) on output variable Average Crack length (ACL) produced due to Electrical Disch...
