OBRABOTKAMETALLOV Vol. 24 No. 4 2022 technology Figures 4–7 show graphs of the cutting force component Fyz for feeds (Sz) of 0.01 – 0.04, respectively, used in the bending analysis of the cutter. Fyz was calculated from the Fy and Fz components. Cutting was done perpendicular to the laser scanning direction to determine the maximum values of the cutting force arising from blows, i.e., the most unfavorable conditions were chosen for the study. As a consequence, peaks and valleys in the cutting force values are observed in the graphs. The cutting force peaks are in the middle of the weld bead, and the valleys correspond to the positions between the weld beads. To avoid differences in the cutting force results and to give a homogeneous change, machining should be done in the scanning direction. The graphs also show that an increase in the feed leads to an increase in cutting force. Similar results were obtained in [21]. A regression analysis was performed to establish the functional dependence of the cutting force component and the feed per tooth. For this purpose, the five maximum values were selected for each feed. The values of the cutting force component are presented in Table 3. Fig. 4.
