Summary, etc. <span lang="EN-GB">The present study engrossed with the functional relationship between the input and output parameters of the electric discharge machining (EDM). Four controllable machining parameters, viz. </span><span lang="EN-GB">gap voltage (A), current (I<sub>p</sub>), duty cycle (C) and pulse on time</span><span lang="EN-GB"> (T<sub>on</sub>) have been chosen to ascertain the electrode wear rate (EWR) and surface roughness (SR) of AISI 420 material with copper electrode. Through Taguchi method, a design of experiment developed and it has been used to perform the experiment based on L16 orthogonal array (OA). During machining of AISI420, the highest influencing factor in EWR is I<sub>P</sub> and least is C. Similarly, for SR T<sub>on</sub> is most and C is least significant factor. From analysis of variance (ANOVA), for EWR, </span><span lang="EN-IN">I<sub>P</sub> is having most significant 79.43% contribution and C is having least significant 2.36 % contribution. Similarly, for SR, T<sub>on</sub> is having most significant 39.95% contribution and A is having least significant 11.79 % contribution</span>
