Документ Determination of rational technical parameters of heavy machines with the help of a data bank(Національний технічний університет "Харківський політехнічний інститут", 2023) Vasylchenko, Y.; Shapovalov, M.; Stankova, M.; Zakovorotniy, O.; Stankov, D.Документ Methodology for the development of a model for managing the quality and productivity of shaping when processing hardened coarse-modular gears(ФОП Тарасенко В. П., 2020) Kovalov, V.; Vasylchenko, Y.; Shapovalov, M.; Antsyferova, O.; Kamchatna-Stepanova, K.Документ Results of industrial testing of carbide cutting tools by pulsed magnetic field treatment and the effect on the increase of the cutting process efficiency(Національний технічний університет "Харківський політехнічний інститут", 2021) Kovalev, V.; Klymenko, G.; Vasylchenko, Y.; Shapovalov, M.; Antsiferova, O.; Maiskykh, I.The task of increasing the efficiency of machining parts on heavy machines was determined, scientifically substantiated and solved by hardening a carbide tool the pulsed magnetic field processing (PMFP). The efficiency of machining of parts is understood as an increase in its productivity, a reduction in the cost and costs of tool materials, and an increase in instrument reliability. The working conditions of cutting tools at heavy engineering enterprises are analyzed. The wear resistance of carbide cutting tools, which have been strengthened by the PMFP, was investigated using forced test methods and modeling of the cutting process. The mechanism of changing the properties of a hard alloy under the action of a pulsed magnetic field is established. The main factors affecting the change in the wear resistance of a hard alloy under the action of a pulsed magnetic field are identified. The effect of pulsed magnetic field processing on the performance of carbide cutting tools under production conditions is investigated. The effect of hardening on productivity, cost of operation and instrumental costs is established. The interrelation of the parameters of the PMFP, the parameters of the process of machining parts and production efficiency is investigated. A statistical model has been developed that allows determining the productivity of mechanical processing depending on the properties of the tool material and the processing parameters of a pulsed magnetic field.Документ Quality management of cutting tools on heavy machines(Національний технічний університет "Харківський політехнічний інститут", 2021) Klymenko, G. P.; Vasylchenko, Y.; Donchenko, Ye.The work is devoted to improving the efficiency of cutting tools on heavy machines by developing a quality management system for its operation, determining rational operating regulations and developing general machine-building standards for cutting. The developed model of the tooloperation control system for the first time allowed to systematically consider the structure and relationships of all components of the process. The qualimetric approach to the tool operation process made it possible to develop methods for quantitative assessment of the process quality and substantiate the structure of the preparatory information subsystem.Документ Modeling of cutting tools wear for lathes(Національний технічний університет "Харківський політехнічний інститут", 2020) Klymenko, G. P.; Vasylchenko, Y.; Kvashnin, V. V.A mathematical model to estimate the average number of parts, processing which is possible to achieve the criterion of maximum allowable wear on the back of the cutter heavy lathe, and the maximum allowable amount of tool material, removed from the front surface of the tool. Experimental equipment for measuring tool wear has been developed. Insert wear curves derived from industrial test results. Confirmation of the adequacy of the models of the instrument gives a possibility of their adjustment to the basic criteria of their dullness.
