Emerging nontraditional micromachining techniques like electrochemical discharge micromachining (ECDM) and laser micromachining are ideal for micro-processing of nonconducting brittle materials like glass. Glass’ low machinability is a significant obstacle, though, and it needs to be overcome. The bottom surface of the microgrooves produced by ECDM is typically irregular and correlated with protrusion structures, while the frames, which frequently have overcutting and apparent wave formed HAZs, are not straight. Additionally, the cross segment created by the laser has a considerable taper and a V-shape. This study suggested the laser aided ECDM for glass microgrooving, which unites ECDM and laser micromachining, to address these issues. The single and hybrid processing techniques were examined for their morphological characteristics in this study. The outcomes demonstrate that ECDM produced tubular protrusions at the microgrooves’ base. The cylindrical protrusions were repositioned after the laser processing of these microgrooves. The microgrooves’ edge quality was still subpar, though. So, to obtain microgrooves with superior edge quality, the laser is employed to create them first. Then, ECDM is employed to change the cross-sectional shape from a V-shape to a U-shape, improving the taper of the microgrooves.
