Conical micro-grooved texture was fabricated on the tool rake face using laser texture technology. Metal cutting tests were conducted on AISI 1045 steel with conventional and developed tools for various cutting speeds (80ˋm/min to 160ˋm/min) and conical angles of micro-grooved texture (2ˋ∼ to 5ˋ∼) under flood lubrication condition. The effect of conical micro-grooved texture on the tool cutting force, tool每chip friction coefficient, surface roughness of the machined workpiece, and wear of the tool rake face was determined. Unlike the conventional tools, the conical micro-grooved tools successfully resulted in reductions in metal cutting force, tool每chip frictional coefficient, surface roughness of the machined workpiece, and wear of the tool rake face. These reductions were more noticeable than those of conventional tools with increases in the cutting speed and conical angle of the micro-grooved texture. Detailed research indicated that conical micro-grooved channel exhibits a directional motion characteristic of liquid, which accelerated the infiltration of cutting fluid at the tool每chip interface. Substantial cutting fluid was supplied and stored at the tool每chip interface for the conical micro-grooved tools. Therefore, the conical micro-grooved texture on the tool rake face showed evident advantages in improving tool每chip friction and tool cutting performance. The main contribution of this study is proposing a new conical micro-grooved texture on the tool rake face, which improved tool每chip friction and tool cutting performance %K Tool每chip friction property %K WC-TiC/Co cemented carbide %K laser texture technology %K conical micro-grooved texture %K cutting fluid %U https://journals.sagepub.com/doi/full/10.1177/1350650118804907
