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.Документ Automation of technological preparation of metal working on heavy machine tools(Національний технічний університет "Харківський політехнічний інститут", 2018) Klymenko, G. P.; Kvashnin, V. V.The programs for selection of the cutting tools construction and cutting regimes are working in unrestricted surroundings elaborate of addition SharpDevelop in language C#. By the appendix of Cosmos of the program SolidWorks the areas of plate break-age and tensions distributing arising up in it at the different values of cutting force are certain. Based on the conducted researches of durability the rational structural parameters of collapsible chisels, in particular, thickness of plate are grounded that provides the increase of efficiency of treatment of details a hard-alloy instrument on the heavy machine tool.
