“…These improvements were attributed to storage of powder chips and derivative cutting because of the textures. Rajurkar and Chinchanikar (2024) implemented six different textures comprising of dimple and channel micro-textures with 0°, 45° and 90° angles and a combination of triangles, squares and dimples on the rake face of tungsten carbide cutting inserts by the use of fiber laser [23]. They concluded that dimple and channel micro-textured tool with 90° texture angle performed the best of all the textures in terms of average tool life, cutting forces and surface finish.…”

Tool life is an important criterion in machining. So, to improve the tool life considering the flank wear, a novel technique of surface texturing is implemented on the flank face of the cutting tool. Two different types of textures viz. dot textures (DT) and groove textures (GT) perpendicular to the cutting edge are fabricated on the flank face of the ceramic and coated carbide tool using micro-electric discharge (µ-EDM) machining. Machining is then carried out on hardened H13 steel with both textured and non-textured (NT) tools. The machining performances are considered as surface roughness, flank wear and cutting temperature which are compared for both coated carbide and the ceramic tool for DT GT and NT. The surface roughness and flank wears during machining with DT are found lesscompared to GT and NT tools for both ceramic and coated carbide. Other hand, surface roughness and flank wears are found less in ceramic tool machining compared to coated carbide tool machining for textured as well as non-textured. The temperature generated at the tool-workpiece interface is higher for the ceramic tool machined surface reveals the formation of white layer which is found more for ceramic tool in terms of thickness and its micro-hardness. The surface produced during machining by textured and non-textured ceramic tool is more lustrous as compared to textured and non-textured coated carbide tool.
