Abstract
The aim of this work is to determine the influence of reversible smoothing parameters on the stiffness index of the stress state scheme and to identify rational parameters for the strengthening process. The research was carried out using the software SOLIDWORKS 2019 (for 3D design) and the finite element method based on the computer program ANSYS Workbench 19.1 (for construction of the mathematical model). In order to obtain the optimal value of the stiffness index for the stress state scheme of parts reinforced by reversible smoothing, the Microsoft Visual Studio 2012 computer program was used, with programming in Python to identify rational parameters for reversible smoothing. The influence of the main technological parameters of reversible smoothing on the formation of the maximum residual stress intensity and the stiffness index of the residual stress scheme in strengthened parts was determined. On the basis of the statistical analysis of the obtained data, rational strengthening modes have been established, which ensure the formation of the maximum possible stiffness index of the stress state scheme in the deformation zone: the longitudinal feed rate in the range of 0.07–0.08 mm/rev; the rotation frequency of the blank in the range of 280–300 rpm; the radial stress value in the range of 0.25–0.28 mm; the initial setting angle of the working tool at 90º; the amplitude of the reversible rotation angle of the working tool in the range of ±55º–±60º; and the reversible rotation frequency of the working tool in the range of 270–300 double pass per min. The rational reinforcement modes obtained by reversible smoothing make it possible to achieve the maximum possible high rigidity of the stress scheme, resulting in improved mechanical properties of the machined parts. Future research could be directed towards refining the mathematical models describing the reversible smoothing process and carrying out experimental work to identify the optimum machining modes for different materials.
