OBRABOTKAMETALLOV technology Vol. 27 No. 2 2025 Next, to find the radial displacement of the cutting tool at the maximum point, the Mohr integral method or the Vereshchagin method can be used [22]. Fig. 10 shows the dependence of the radial offset of the cutter on the feed per revolution. Analysis of the presented data allows us to conclude that the measured values of the maximum offset of the tool differ from the calculated ones by no more than 17 %. Thus, using the differential equation described above, it is possible to analytically calculate the radial displacement of the tool at the maximum point and numerically predict the magnitude of the error in the holes obtained during finish boring. This paper examines the main factors influencing the accuracy of the shape of holes obtained by boring. The use of the developed algorithms and models enables the technologist to assign technological processing parameters depending on the accuracy specified by the service purpose. b Fig. 10.Dependence of the radial displacement of the boring cutter axis on feed rateper revolution: a – material: steel 0.4 C-Cr; b – material:aluminum alloyAl-Cu-Mg-Mn(quenched and naturally aged aluminum alloy, containing ≤ 94.7 % Al; ≤ 4.9 % Cu; ≤1.8 % Mg; ≤ 0.9 % Mn) а
