Increasing the operational life of the cutting tool based on stress relieving

Abstract

The paper covers the results of studying the influence of internal stresses arising in the manufacture of changeable polygonal plates of TC type hard alloys on the resistance of the cutting tool and the possibility of relieving them by preheating the cutting plates before cutting. A method and a special design are proposed for preheating changeable polygonal plates in order to relieve internal stresses in tool hard alloys and increase the resistance of the cutting tool.
