A generous development of electrical discharge machining method has been stimulated in the province of metal matrix composites materials. In this extant work, the optimal condition for various output responses specifically circularity, cylindricity, perpendicularity and radial over cut are exposed by employing grey relational analysis procedure by optimizing the input process parameters alike pulse on time (T on), peak current (I) and gap voltage (V). The Hybrid Metal Matrix Composite material is evolved by handling the stir casting approach and then machined by exploring the input parameters using L 27 orthogonal array. From the consequences of grey relational grade, a response table was discovered to elect the optimal conditions of the individual parameter. The most contributing input parameter is current with 69.08%, which is determined from the ANOVA table. Finally, the optimal conditions which were acquired from the response table are peak current of 12 A, pulse on time of 50 µs and gap voltage of 30 V and also verified through an authentication test which illustrated that optimal process parameters are competently improved by 0.1452 when compared to the predicted parameter. The machined surface is analysed using a scanning electron microscope. The results palpated that the peak current increases the number of microvoids and size of the crater was increased and the poor surface finish was achieved.

“…They coated the electrode with acrylonitrile-based polymer by fusion deposition method, which increased the electrical conductance of the electrode and increased the machining rate significantly. Mathai et al [15] adopted the planetary tool movement on EDM to investigate the process parameters for titanium alloy. Along with this planter movement, they fabricated square holes with two types of electrodes materials (i.e., copper and graphite).…”

Electrical discharge machines (EDM) are widely employed in machining components containing complex profiles of hard-to-cut and machining materials. However, the fabrication-of-tool time for the EDM process is excessively high in the traditional machining method, which significantly affects the machining rate. Therefore, in this paper, a powder metallurgy (PM) technique is employed to fabricate the tool electrode using copper (Cu), titanium carbide (TiC), and zirconium silicate (ZrSiO4) for different combinations. An L18 orthogonal array (OA) is planned using the following input parameters: three types of tools (Cu, Cu90, Cu80), peak current (PC) [A], pulse on time (PT) [µs], and gap voltage (GV) [V]. The performance of EDM is evaluated through the material removal rate (MRR), tool wear rate (TWR), and surface roughness (SR). The process parameters are optimized using two different techniques: the technique for order of preference by similarity to the ideal solution (TOPSIS) and grey relational analysis (GRA). TOPSIS and GRA optimization techniques produce the same optimal parametric solution for less TWR, SR, and higher MRR with the combination of the Cu90 tool, E8 APC, 15 µs pulse PT, and 75 V GV. Based on the ANOVA table of TOPSIS, pulse on time plays a major role, contributing 46.8 % of the machining performance; peak current shows the most significant contribution of 39.3 % of the machining performance using GRA values. Furthermore, the scanning electron microscope (SEM) image analyses are carried out on the machined workpiece surface to understand the effect of tools on machining quality.
