THEORETICAL FOUNDATIONS OF THE PROCESS OF PUNCH AND DIE CUTTING OF TEETH

Abstract

This article discusses the process of cutting teeth on saw blades in the interaction of the punch and the matrix. Modeling of the punching process analyzes the stress distribution in the contact area of the punch and the workpiece. Unlike traditional approaches using the Hertz model, a model of specific stress distribution is used for punching, taking into account the features of the punching process. A system of equations is compiled, which is a generalized mathematical model of the cutting process, taking into account all the aspects considered earlier: stress distribution, fracture criterion, crack growth, process dynamics, tool wear, thermomechanical effects and the condition for the formation of a cut.
