Analysis of the material model of C45 steel for the simulation of the machining process

Article presents the results of turning process simulation research, carried out with a use of specialized software based on FEM method. On the basis of test results, temperature distribution on the rake face of the cutting tool was determined. C45 steel was adopted as the workpiece material, and the sintered carbide, without a protective coating – as the tool material. Material models of the C45 steel were built using the Johnson-Cook constitutive equation and material constants available in the literature. Research scope included the simulation of the orthogonal turning process, considering different levels of rake face wear.
