“…An increased level of vibration not only reduces the service life and the reliability of its elements but also leads to a decrease in the quality of processing and a decrease in productivity, the efficienc of machining decreases, which is especially important in the machining of materials prone to hardening, such as titanium alloys, stainless steels, etc. The known methods of vibration monitoring using neural networks [2,3,4,5,6,7,8,9] have their limitations due to the complexity of physical and mechanical processes in the MDTD (machine-device-tool-detail) system (here it is necessary to decipher) during machining. The considered methods in the sources [10,11,12] to reduce the level of vibrations do not fully cover the arsenal of tools and methods.…”

The article describes the main causes and sources of impulse - vibration effects on the elements of the "machine tool - device - tool - detail" system. The paper deals with the development of methods for increasing the efficiency of machining due to the rational choice of technical solutions for vibration protection by design and technological methods with the use of vibration monitoring. A criterion for the efficiency of machining is given, which is determined by a matrix using scalar parameters, which are traditionally used for vibration diagnostics. A complex criterion for the quality of machining has been determined, which describes the indicators of the geometric accuracy of the machined surface. The block diagram of algorithms for selection and rational use of structural and technological methods of vibration protection of technological system elements is presented. Vibration and technological criteria for choosing solutions for vibration protection and monitoring are proposed. The implementation of the developed algorithms is considered on examples of machining and numerical estimates are given, confirming the high quality of the developed solutions.
