The aim of the work is to create theoretical bases, technical means and software products for control of regenerative oscillations during turning, milling and grinding using modulation of cutting speed Methods of investigation - experimental study of regenerative self-oscillations vibrations. The results of the research work summarize the current results on the investigation of the mechanisms of excitation of oscillations and the establishment of regularities of these phenomena, the static and dynamic characteristics of elastic systems in turning and final milling are determined; the conditions for the appearance and characteristics of regenerative self-oscillations during turning and final milling are revealed; The dependences of the influence of the static and dynamic properties of the elastic system of a thin-walled detail on the features of excitation mechanisms and vibration suppression in a wide velocity range of various milling conditions are determined. The predicted assumptions of the development of the object are the determination of the influence of the parameters of the technological system on the level of regenerative self-oscillations during turning and end milling.
