Résumé
Edge polishing is a critical process in stones manufacturing and transformation as this process affects both aesthetic quality and manufacturing efficiency. This study investigates the impact of tool geometry, grit size, and cutting conditions on surface quality, tool wear, and process optimization in wet edge polishing of granites. Four tool shapes, eased concave edge, eased chamfered edge, ogee edge, and half-beveled edge, were used, each with three grit sizes (G150, G300, G600). Cutting parameters included spindle speeds of 1500, 2500, and 3500 rpm, along with feed rates of 500, 1000, and 1500 mm/min.Surface quality was assessed by measuring roughness profiles and Ra-values under varying conditions, while tool wear and cutting forces were analyzed to evaluate polishing efficiency. Results indicate that finer grits improve surface finish but increase processing time and tool wear. Higher spindle speeds enhance material removal but generate greater cutting forces, potentially affecting tool longevity. The interaction between edge geometry and process parameters revealed that eased concave and ogee edges require lower energy input and produce superior surface finishes.Process optimization was performed to identify the best balance between surface quality and efficiency. Statistical analysis demonstrated that an optimal combination of G600 grit, a spindle speed of 2500 rpm, and a feed rate of 1000 mm/min provides a favorable compromise between polishing performance and tool durability. Additionally, cutting forces obtained during the edge finishing of black granite were marginally higher than those obtained for white granite. These findings contribute to improving the granite edge polishing process by optimizing cutting parameters to enhance productivity while maintaining high-quality standards.
