UNIT 1 METAL CUTTING AND CHIP FORMATION

WebThe changing of shear angle and shear plane temperatures in cutting of steel in the beginning of cutting is shown in this paper. Keywords: metal cutting, friction, Finite Element Method, shear angle 1. Introduction Modelling of metal cutting requires prediction of machining with its parameters such as cutting forces, stresses, and strains. A shear zone is a zone of strong deformation (with a high strain rate) surrounded by rocks with a lower state of finite strain. It is characterised by a length to width ratio of more than 5:1. Shear zones form a continuum of geological structures, ranging from brittle shear zones (or faults) via brittle–ductile shear zones (or semibrittle shear zon… net off in jaipur
