Cutting performance of positive rake angle inserts under the combined effect of chip breaker and surface micro-texture on the rake face

The fabrication of micro-textures on the chip breakers of the inserts is infrequent and examines on the combined effects of chip breakers, and surface textures of the positive rake angle inserts on chip breaking, cooling, lubrication, and friction wear are relatively scarce. In this research, a nanosecond laser was used to create textures on the insert of the chip breakers. Under wet and dry cutting environments, the cutting force, cutting heat, chip breaking, and insert wear of traditional and textured inserts were compared and analyzed. The synergistic effect of chip breaker and surface micro-texture on cutting performance is discussed. The result indicates that the combined effect of chip breaker and surface micro-textures reduces cutting forces and cutting heat, diminishes insert wear, and facilitates chip breaking. The result of this study provides an idea for an approach to the development and fabrication of high-quality inserts.
