Description
This research work describes the optimization of parameters in electric discharge machining (EDM) of AlFeSi (AA8011) alloy composite using the technique for order preference by similarity to ideal solution (TOPSIS) method. Initially, the AA8011 matrix alloy was synthesized with the addition of 10 wt.% TiO2 particles through the stir casting route. Scanning electron microscopy (SEM) was used to examine the morphology of the synthesized composite, which revealed that the TiO2 particles were evenly disseminated within the alloy. The machining factors, such as peak current (Ip), pulse-on time (Ton and pulse-o time (Toff), were chosen as input, whereas the material removal rate (MRR), the surface roughness (SR), and the tool wear rate (TWR) were selected as the output responses. According to the L9 (33array, the machining experiments were conducted using a brass (Br) electrode. By employing the TOPSIS method, the optimum combination of variables was determined. Based on the analysis, the Ip of 10 amps, Ton of 200 s, and Toff of 30 s provide the highest MRR (0.2379 g/min) with lower SR (3.284 m), and TWR (0.0258 g/min). ANOVA ndings exhibited that Ton was found to be the primary noteworthy factor contributing 50.67%, next by Toff (32.98%) and Ip (13.12%), respectively. Finally, the conrmation trials were carried out using the optimal parameters, which veried the predicted results. 2026 World Scientific Publishing Company.
