Manufacture of Hardmetal Cutting Plates Using Self-Propagating High-Temperature Synthesis

Abstract

A process for producing hardmetal cutting plates (synthetic cutting tool material modi¬fication) has been developed and implemented in practices. It is established that the most rational and economically sound option is to introduce several die toolings with relevant operational features in the manufacture of products by self-propagating high-temperature synthesis. Advantages of the index characterizing stress stiffness have been revealed. They involve one-to-one correspondence between the values of this index and potential patterns of plane stress. Coordinates for analytical representation and geometrical interpretation of limiting state criteria are proposed.
