Analysis of the material model to simulation of the machining process

The paper presents the results of 2D simulation, which were carried out to determine the state of the the cutting edge during the machining process. Steel AMS 6265 was selected as a material model, which was based on the Johnson-Cook equation. Sintered carbide was adopted as a tool material. Parameters of the machining process, like cutting speed and feed rate were changed in simulations. The impact of these changes on the forces in the X and Y axes of the cutting tool and the changes in temperature occurring on the rake face have been observed. The scope of the research included the changes in the Johnson-Cook material model: dynamic hardening coefficient - C, thermal softening exponent - m and strain hardening exponent - n.
