Abstract:	The article analyzes the characteristic features of the vibration cutting process with ultrasonic frequency (UF), which is one of the most effective methods that reduces labor costs and improves their quality and reliability during the mechanical processing of particularly hard and brittle materials. To stabilize the amplitude and frequency, changing as a result of changing the resonant frequency of the vibrator-concentrator-part (VCP) oscillatory system during processing, linear and relay-type generators are proposed that operate on the basis of excitation of the natural frequency of the mechanical vibration system VCP, and these generators are modeled and synthesized using MATLAB/Simulink. With the development of modern machinery and technology, new materials with improved mechanical properties are created, on the basis of which critical parts are manufactured, where high accuracy, quality, and reliability indicators are required. In the machining process, to stabilize the amplitude and frequency, which change as a result of the change in the resonant frequency of the vibrator-concentrator-part (VCP) oscillatory system, generators of the linear and relay type are proposed, which work on the basis of the excitation of the own frequency of the mechanical vibration system of the VCP. These generators are modeled and synthesized in MATLAB/Simulink. The obtained mathematical models and curves of the transition process show that, despite the change in the disturbing factor when the coefficient of friction is changed, conservatism is ensured, as a result of which there is an opportunity to improve the quality of surfaces machining of parts.
