The advanced manufacturing and machining techniques are adopting a population-based metaheuristic algorithm for production, predicting and decision-making. Using the same approach, this paper deals with the application of bees algorithm and differential evolution to forecast the optimal parametric values aiming to obtain maximum material removal rate during electrochemical discharge machining of silicon carbide particle/glass fiber–reinforced polymer matrix composite. The bees algorithm follows swarm-based approach, while differential evolution works on a population-based approach. The experimental design was prepared on the basis of Taguchi’s methodology using an L16 orthogonal array. For the experimental analysis, the main variables in the process, that is, electrolyte concentration (g/L), inter-electrode gap (mm), duty factor and voltage (volts), were selected as main input parameters, and material removal rate (mg/min) was adjudged as output quality characteristic. A comparative investigation reveals that the maximum material removal rate was obtained by the parametric value proposed by differential evolution that follows the bees algorithm and Taguchi’s methodology. Furthermore, the results prove that the differential evolution algorithm has better collective assessment capability with a rapid converging rate.

The electrochemical discharge machining (ECDM) process is a promising advanced machining process to remove material from electrically non-conductive materials like glass, ceramics, etc. Till now fabricating a channel with a high aspect ratio on the glass surface is a challenging job as the generated gas bubbles are escaped from the machining area without developing gas film and consequent discharges. In this study, two novel approaches of tool feeding such as side feeding and bottom feeding along with usual top feeding approach have been introduced to keep the gas bubbles at the tool-electrode tip so that the development of gas film and spark discharge are taken place uniformly at the machining zone. Tool-electrode feeding at the bottom surface and at the side surface of workpiece have been employed and compared with the usual top feeding tool-electrode at the top surface of workpiece. The concentration of aqueous sodium hydroxide electrolyte and the feed rate of tool are varied for experimental investigations. The side feeding of tool-electrode has been found as the most suitable feeding approach for ECDM process. During side feeding approach, the overcut of the machined channel has been reduced by 11% as compared to that of top feeding. Also, depth of the channel has been increased significantly during machining by side feeding and bottom feeding. The tool wear has been reduced more in case of side tool-feeding approach than other two tool-feeding approaches.

In the present work, attempts have been made to optimize the EDM process with an aspect of surface modification of AISI P20+Ni die steel using powder metallurgy (P/M) electrode. Experiments have been performed according to central composite rotatable (CCD) design using response surface methodology (RSM). Effects of compaction pressure (Cp), peak current (Ip), pulse-on time (Ton), and duty cycle (τ) were correlated with surface roughness (SR) and microhardness (MH). Adequacy of mathematical model has been checked by performing ANOVA. Composite desirability approach was used to obtain optimal set of parameters for minimum SR and maximum MH. The errors between the predicted and experimental value of responses at the optimal set of parameters for SR and MH maintain within 5.26% and -3.64% respectively. Scanning electron microscope and energy dispersive spectroscopy analysis confirmed the transfer of P/M electrode material on the work surface. The result indicates three times improvement in microhardness of EDMed surface.
