Abstract
The scientific work represents a research of the cutting process in order to determine the influence of the cutting tool extension’s length from the tool holder and the cutting forces that occur during processing and corresponding to different values of the removed layer on the formation of the quality of the surface layer of parts during turning. As a cutting tool, the research used a PCLNR2525M12 straight-turning tool with replaceable T15K6 carbide inserts. Steel cylindrical workpieces with a diameter D = 40 mm (steel grade - 30) were used as workpieces. Cutting was carried out at three different cutting depths: 0.4, 1, 1.5 mm. The feed rate and spindle speed throughout the experiment were constant and were equal to s = 0.1 mm/rev, n = 1000 rpm, respectively. The geometric deviations of the cutter from the theoretical cutting line were determined by mathematical modeling methods. Linear displacements formed due to the stress-strain state of the cutter were used as estimated parameters. The study presents the methodology for preparing and conducting mathematical modeling using the three-dimensional modeling system KOMPAS-3D and APM FEM module. The roughness parameters that occur during turning by cutters with different tool extension with different cutting modes were studied experimentally.
