The paper briefly reviews current scientific publications related to machining of difficult to cut materials and finite element modelling methods (FEM) applied in various chip making processes. Simulations of the orthogonal machining process with regard to define optimal cutting parameters as well as cutting wedge geometry in hole making TiAlN alloy was performed according to test plan based on design of experiment (DoE) methodology. The numerical simulations were performed using commercial finite element software (AdvantEgde), which is suitable to solve complex thermo-mechanical problems occurring in cutting zone during chip making process. A Lagrangian finite element-based model is applied within simulation procedure. Results from experimental simulation were evaluated by main effect and surface response plots.
