Grinyov Y. Increase of application efficiency of universal cutters at the expense of optimization of geometrical parameters of a rotary working part

Object - designs of turning cutters with a rotary working part; the purpose - decrease of the nomenclature of cutter holders and cutting plates, which appear in the system of turning tool, due to creation of universal turning cutters with optimum geometrical parameters of a rotary working part; methods - theoretical methods which are based on fundamental propositions of vector algebra and theoretical mechanics, the modern mathematical tools, mathematical modelling, experimental methods; theoretical and practical results - for the first time techniques of performance of design stages of the modular tool being specific for universal cutters with a rotary working part are developed, it is reduced the nomenclature of purchased turning cutters to 30 % and metal consumption of systems of turning tool up to 20 - 70 %, the new advanced design of universal cutter, having the raised rigidity and a minimum quantity of components, is developed (the Patent of Ukraine 51167); programs of execution of calculations atdesign stages of universal cutters with a rotary working part by means of the computer and recommendations for specification of machining conditions at use of universal cutters are developed; degree of adoption - results of researches are introduced on Etalon plant with economic benefit of 8 000 hrn per year and used in educational process of Donetsk national technical university; sphere of use - design of modular turning cutters and also the axial tools and mills with mechanical fixing of cutting plates, the tool-room and machine-building enterprises with high-variety and piece works.
