Effects of Chromium (Cr) powder concentrations (C p ) and Span‐20 surfactant concentrations (C s ) on AISI D2 hardened steel were evaluated using response surface methodology (RSM) and parameter processing parameter were optimized for optimal parameter conditions using multi‐response desirability function. Responses taken involved material removal rate (MRR), electrode wear rate (EWR) and surface roughness (R a ). The experimental plan was based on the face centered, central composite design (CCD) using version 10.0 of the Design Expert software. The results identified that C p is the most important parameter to maximize material removal rate (MRR) and minimize electrode wear rate (EWR) and surface roughness (R a ). With the topmost desirability solution, the suggested optimum parameter condition of C p and C s were 2.155 g/L and 10.000 g/L, respectively.
