“…Therefore, 81 (3 × 3 × 3 × 3) combinations were considered. However, according to the L-27 orthogonal array design, the samples could be developed or made in only 27 combinations and present outputs with the same reliability as if they were taken into account individually 26,27 . Employing the design of the experiment method in Minitab-19 software, orthogonal array design L-27, and the DOE (design of experiments), as shown in Table 4, Table 3.…”

The hybrid Electric Discharge Machine (PM-EDM) is the latest advancement in the removal of hard materials from workpieces while enhancing their performance and characteristics. This research project is focused on optimizing key process parameters, including material removal rate, tool wear, residual stresses, and surface finish. The approach utilized in this study involves employing the standard deviation-based objective weighting method in conjunction with GRA (Grey Relational Analysis) optimization to improve the hybrid PM-EDM process when applied to EN-31 material. Experimental runs were conducted to assess the impact of various input factors such as pulse on time, duty cycle, discharge current, and concentration of metallic powder. The GRA (Grey Relational Analysis)-based Taguchi method was employed for this purpose, and the experimental design followed an L-27 orthogonal array within the framework, facilitated by the use of minitab-20 software. A total of 27 experiments were conducted, encompassing diverse combinations of process parameters. Subsequently, an ANOVA (Analysis of Variance) was performed to scrutinize the impact of various inputs of discharge current, pulse on time, duty cycle, and powder concentration on MRR (Material Removal), TWR (Tool Wear), Ra (surface finish), and Rs (Residual stress).

“…Notably, the concentration powder played a crucial role in influencing the spark gap. For instance, when the powder concentration was maintained at 4 g/l, the plasma channel remained small, leading to the formation of intense craters on the workpiece 26,27 . If the discharge current and pulse on increased, a higher erosion rate was achieved.…”
