NUMERICAL AND ANALYTICAL INVESTIGATION OF THE ORTHOGONAL CUTTING PROCESS OF C45 MEDIUM CARBON STEEL

Martin NECPAL, František JURINA, Marcel KURUC

Abstract


This study builds on previously published experimental research of the machining process by applying analytical and numerical modeling to better interpret the observed results. The analytical Oxley model and a 2D orthogonal cutting simulation using FEM DEFORM software are employed to investigate the cutting zone behavior for C45 medium carbon steel, a commonly used reference material. The FEM analysis reveals that the distribution of deformations in the shear plane is not constant, in contrast to the assumption of the simplified Oxley machining model. The FEM predictions show the closest agreement with the experimental findings and provide additional insight into cutting phenomena that are difficult to access experimentally. The combined use of validated analytical and numerical models complements the earlier experimental work, deepens the understanding of machining mechanics, and supports the development of improved machining strategies, cutting tool design, and enhanced production efficiency.
