description The invention discloses a laser surface strengthening process for a cutting edge of a numerical-control tool, and the laser surface strengthening process can effectively prolong service lives of partsby selecting certain laser scanning conditions to perform strengthening treatment on the surface of the cutting edge and effectively improving surface hardness, wear resistance, corrosion resistance,strength, high-temperature resistance and the like of the cutting edge. The laser surface strengthening process comprises the following steps: 1) performing surface clearing on a cutting edge part ofa to-be-strengthened tool; 2) selecting a laser head with adjustable laser spots, and setting operation parameters of the laser unit; 3) controlling the laser unit to scan the cutting edge part of the tool according to the parameters set in the laser step; and 4) accomplishing scanning of the cutting edge part once, and quickly cooling the cutting edge part to form a uniform laser quenching layer. The process method disclo
