Description
Summary:Modeling chips formation is a highly complex task because numerous mechanical, thermal, hydrodynamic, tribological and chemical phenomena are present in a coupled way. In three dimensional simulations also the contact problem may bring extra numerical complications. That's why many simulation work deals with the two dimensional model of cutting. In this paper we demonstrate our model calculations on the cutting wedge as it works in planning. We have built up a two-dimensional model and solved it. Result are in good agreement with general experiments, describes thermal fluxes, temperature and stress peaks, typical places of wear. [PUBLICATION ABSTRACT]
