“…To determine the optimal setting of the EDM parameters ( I , T on and T off ) at which Δ D and Δ H are minimum, the desirability function approach was used [ 21 ]. The desirability approach is a local optimization technique that is used to determine the optimum setting within the specified range.…”

“…To validate the machining results, the DA of the machined cavity achieved using the novel electrodes is compared with that of solid copper (SC) electrodes and electrodes fabricated by FDM and metallized using electro-deposition method (FDM-EM) already reported in literature under similar machining conditions. The optimal setting of the EDM parameters for minimizing both Δ D and Δ H is also determined using the desirability function approach, which is an important optimization method widely used in machining, casting, forging, and other medical applications [ 21 ].…”

In the present study, cylindrical ABS P400 polymer parts (diameter 6.5 mm) to be used as die-sinking EDM (electric discharge machining) novel electrodes were fabricated using a fused deposition modeling (FDM) process. To meet the conductivity requirement in EDM, ABS parts were metallized using an innovative method that comprised putting aluminum–charcoal (Al–C) on them followed by their copper electroplating. Real-time EDM of the mild steel workpiece was performed using novel electrodes, and machining performance of the electrodes, measured in terms of dimensional accuracy, i.e., change in diameter (ΔD) and change in depth (ΔH) of the cavity, under varying levels of three EDM factors, i.e., current (I), pulse on time (Ton), and pulse off time (Toff), was investigated. Machining results were analyzed using analysis of variance (ANOVA), perturbation graphs, and 3D surface plots. The optimal setting of the EDM parameters for minimizing ΔD and ΔH was determined using the desirability function approach. The suitability of the novel electrodes for EDM was ascertained by comparing their machining results with those of solid copper (SC) electrodes and electrodes fabricated by FDM and metallized using the electro-deposition method (FDM-EM), already reported in the literature, under similar machining conditions. From the results, it was found that ΔD and ΔH were less when EDM was performed using novel electrodes.
