D ISCUSSION

s a result of the experiment and analysis of the obtained mathematical models, it was revealed that:  The Analysis of the oscillations of the cutting force components (Fig. 5) for the entire time of the pass allowed defining the steady-state cutting area in all the experiments carried out. As a result of 54 experiments the A
