ABSTRACT:
A method for extending the life of a cutting tool includes shot peening the surface of the tool, including all cutting edges thereof, with substantially spherical shot peening media of glass beads. Maximum life extension is achieved by optimizing the parameters of the peening process, including the Almen intensity and the shot size and uniformity. Cutting tools, especially steel tools, shot peened in accordance with the present method display many-fold increases in life.
