Experimentation into Electrochemical Discharge Milling for the Generation of Cavity on Glass Sudip Santra, Biplab Ranjan Sarkar, Biswanath Doloi, Bijoy Bhattacharyya Journal of Advanced Manufacturing Systems, 2025 The development of electrochemical discharge machining (ECDM) and the use of electrically nonconducting materials in microelectromechanical systems (MEMS), biomedical applications and making lab-on-a-chip devices are increasing tremendously. In this study, the performance of electrochemical discharge milling was improved by introducing the bottom-up movement of tool-electrode, i.e. vertically upward tool-feeding technique. The development of gas film model was compared with the actual gas film shapes to find out the problems associated with the existing tool-feeding technique and the advantages of vertically upward tool-feeding technique. Single channels were generated on the soda lime glass workpiece to analyze and obtain appropriate process parameters for good-quality channels. Applied voltage, electrolyte concentration and tool feed rate (TFR) were varied to get good-quality channel. It was achieved at the process parameters of an applied voltage of 40 V, an electrolyte concentration of 5 M and a TFR of 50 [Formula: see text]m/s. With this parametric setting, four consecutive parallel channels were generated to get cavity on the soda lime glass. Rectangular-shaped cavities were fabricated by adopting three different strategies to minimize the problem of material deposition along the border of two adjacent parallel channels. These rectangular cavities were observed under a microscope to measure and obtain the surface topography which revealed the usability of third strategy of generating smooth and uniform cavity with lower surface roughness ([Formula: see text][Formula: see text]). A rectangular cavity of 0.247-[Formula: see text]m surface roughness with smooth corners and edges was obtained at 40 V of applied voltage and 50 [Formula: see text]m/s of TFR.
Investigation through novel tool-electrode feeding approach on electrochemical discharge machining of glass Sudip Santra, Biplab Ranjan Sarkar, Biswanath Doloi, Bijoy Bhattacharyya Proceedings of the Institution of Mechanical Engineers Part B Journal of Engineering Manufacture, 2023 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.
