Документ Guidelines to settlement and graphic work on the discipline "Interchangeability, standardization and technical measurements"(2023) Riazanova-Khytrovska, N.; Kozakova, N.Methodical instructions to settlement and graphic work on the discipline "Interchangeability, standardization and technical measurements" for foreign students of mechanical engineering specialties NTU "KhPI". Methodical instructions contain theoretical material, but are step-by-step instructions that allow foreign students to reduce the time for completing and completing work. The given text elements allow you to reduce the time of writing the work, and the sketches of the drawings - in general, to spend time only on drawing dimensions, tolerances of dimensions, limit deviations, tolerances of shapes and the location of surfaces, that is, directly on what constitutes the content of the discipline. The methodical instructions also provide literary and normative sources, which determine the initial and reference data, where you can review the theoretical material of the discipline and see examples of performing calculation-graphic tasks and design drawings. Each action during the performance of the work is accompanied by tables, figures and attachments that must be used when performing sections of the work.Документ 3D methodology of research of diamond-abrasive machining process(Національний технічний університет "Харківський політехнічний інститут", 2020) Grabchenko, A. I.; Fedorovich, V. A.; Pyzhov, I.; Ostroverkh, Y.; Kozakova, N.Subsystem of computer-generated determination of conditions of manufacturing of defect-free diamond wheels and grinding of superhard materials on the base of 3D simulation of deflected mode of elements of the "SHM crystal grain – metal phase – grain – bond" system at process of diamond wheel sintering and grinding is developed.Документ Theoretical reasoning for efficient use of micro powders in diamond wheels on metallic bonds(Національний технічний університет "Харківський політехнічний інститут", 2020) Grabchenko, A. I.; Fedorovich, V. A.; Pyzhov, I.; Ostroverkh, Y.; Kozakova, N.The article presents theoretical researches of improving the manufacturing process and the subsequent using of grinding wheels from diamond micro powders of diamond on currentcarrying bonds, which allow to reduce the specific consumption of synthetic diamonds in the finishing operations of processing polycrystalline superhard materials It is proposed to use diamond grains with a metal coating in an abrasive tool. 3D analysis of the stress-strain state “diamond grain-coating-bond” system showed ways to reduce the probability of destruction of diamond grains during sintering of the diamond-carrying layer by changing the thickness of the coating, the elastic modulus of its material and other parameters. The calculated low values of the concentration of coated diamond grains provide a significant reduction in their specific consumption in the processing of polycrystalline superhard materials.Документ The methodology of sharpening of blade tools made of superhard materials(Національний технічний університет "Харківський політехнічний інститут", 2019) Fedorovich, V.; Ostroverkh, Y.; Kozakova, N.High durability of the blade tool from superhard materials (SНM), which have unique physical and mechanical properties, creates the prerequisites for its effective use in automated production. However, the widespread use of such tools is constrained by its relatively low reliability during operation. This disadvantage is due to the imperfection of the processes of obtaining SНM: the presence in it residual stresses, internal defects, which appear even after sharpening and thermo-activated finishing. The processes of sharpening of tool blade from superhard materials and cutting with this tool are characterized by high levels of contact pressures and temperatures in the treatment area. Therefore, it seems inappropriate to choose sparing conditions for its sharpening and refinement to ensure the defect of these processes. In connection with this, a new methodological approach is proposed, which makes it possible to determine the cutting conditions and other conditions for sharpening and finishing the SНM blade tool, in which material defects are revealed even at the tool manufacturing stage. To this end, in the software packages COSMOS, ANSYS, NOSTRAN, Third Wave AdvantEdge, thermo-force stress in the cutting edge of the tool simulated under extreme conditions while its operation. This simulations are the initial data for solving the inverse problem – finding conditions (speed, cross feed, normal pressure in the contact) and other diamond grinding modes (physical and mechanical properties of the bond and diamond grains of the wheel, grain size and concentration) according to the well-known stress-strain state cutter from SНM in extreme conditions of its operation. The proposed methodology allows rejecting defective cutters at the stage of their manufacture, thereby increasing the reliability of operation of blade tool from superhard materials.
