Modification of the Surface of a Reconditioned Cutting Tool via Laser Ablation

Abstract

The article discusses the possibility of using pulsed laser ablation of nanosecond duration to modify the surface of a cutting tool after regrinding and restoration. Experimental studies of the resistance characteristics of cutting tools with modified surfaces via laser ablation in air and in liquid have been carried out. It was found that after modifying the surface of cutting plates via laser ablation in air, the wear on the trailing surface of the cutting tool at a processing speed of V = 50 m/min is 8 times less than that of the untreated one, the build-up is 20 times less. The wear of the trailing surface of the plates at V = 70 m/min is 2 times less than that of the untreated sample. The resistance studies show surface modification of the cutting tool increases the tool life of the remanufactured tool, overall tool life and savings in tool costs.
