Item Impact of processing modes and parameters of the working part of the instrument on the surface quality of flat parts during high-speed friction hardening(Видавництво Львівської політехніки, 2017-12-23) Dmyterko, Petro; Novitskyy, Yuriy; Gurey, Volodymyr; Lviv Polytechnic National UniversityImpact of processing modes and parameters of the working part of the tool-workpiece on the quality and surface precision of details during high-speed friction hardening of flat details is developed.Item Optimization of damping parameters of self-oscillations of multifrequency oscillatory system(Видавництво Львівської політехніки, 2017-12-23) Novitskyy, Yuriy; Dmyterko, Petro; Lviv Polytechnic National UniversityDeveloped and researched mathematical model four-mass scheme autoclave machine tools. Influence of parameters of internal friction is analysed in the joints of structural elements machine-tool on relative amplitude of vibrations the cutter and detail. The ambiguousness of influence of parameters of damping energy of vibrations is shown on relative amplitude of the vibrations a cutter and detail.
