Abstract

This paper shows the chip forming morphology of the plastic strain in the chip root in function of the cutting data. The knowledge of strain mechanisms may advance the increase of material removal efficiency thus appoint newer fields of application. The experiments on the examined case hardened steel at 62±2 HRC were carried out at different cutting speeds and feed rates. Our experiments were completed by means of Finite Element Method (FEM) in case of orthogonal cutting. For the simulation the data of experiments done previously were used. In the course of the FEM analysis the occurrence of the adiabatic shear as well as the sawtooth chip forming mechanism were examined. The relationship between plastic strain and the change of cutting data was investigated. In the paper the change of the morphology of chip formation is compared depending on the cutting speed.
