This research focuses on the estimation and assessments of the precision of machining during wire electrical discharge machining (WEDM) using the highly deformed EN AW 7075 alloy, achieved through equal channel angular extrusion (ECAP), for optimal material removal rate (MRR) and improved surface quality. The key factors under investigation in this study include pulse-on time, pulse-off time, peak current, and spark gap voltage, which were chosen based on the application of response surface methodology (RSM). Utilizing mathematical modeling, the study develops a predictive model for the response parameters, and the anticipated machining characteristics exhibit notable alignment with experimental outcomes.
