Exploring MRR in Wire EDM of Titanium Grade 5: A Statistical Analysis

Abstract

The present study delves into exploring how various parameters of the WEDM process influence the material removal rate (MRR) behavior of Titanium grade 5 alloy, employing Taguchi methodology. Four key process parameters, namely pulse on time (Ton), pulse off time (Toff), wire feed (WF), and gap voltage (V), each with three levels, are chosen to effective MRR. Utilizing the L9 orthogonal array (OA), the study examines the impact of these input parameters and their interactions. S/N ratio analysis is employed to pinpoint the optimal conditions for maximizing MRR within the experimental range. Analysis of variance (ANOVA) is conducted to assess the significance of the process parameters. Subsequently, a confirmation test is carried out to validate the efficacy of the chosen design. Results indicate that at the optimal condition, the S/N ratio of MRR has improved by 13.5% compared to the initial condition.
