Vibration is considered one of the effective ways to sharpen billets from difficult materials. The rational purpose of cutting modes with such a process allows you to increase the resistance of the metal-cutting tool, contributes to the creation of conditions to ensure constant crushing of chips. When cutting materials on the lathes of a turning group with the imposition of oscillations to the cutting tool, processes occur in the cutting zone, which differ from the processes arising from sharpening without oscillations.
The article discusses the possibilities of using vibration oscillations when cutting materials. Currently, new materials that have high strength characteristics, viscosity and plasticity are widely used in mechanical engineering, with an increase in the processability: cutting force increases and efficient power spent on cutting; The quality of surface roughness is worsen; the resistance of the cutting tool is reduced; The amount of heat formed in the cutting zone increases and the character of its distribution on the surfaces of the workpiece and the tool changes; the process of forming chips, its shrinkage and type; The intensity of the process of formation of outflow and its form. In this regard, the question arises about the search for rational processing methods, in particular, mechanical processing with cutting on lathes.
In this scientific work, the use of low-frequency oscillations is substantiated, which is the complex vibrational effect on the cutting process with the enforcement of solid chips, removal from the top of the cutter and preventing its formation, while ensuring the presence of a given roughness of the treated surface and an increase in the cutter resistance period. Research work in this direction is relevant and requires further research.

In June 1994 the 2nd International Scientific and Technical Conference "Application of vibrations for technological purposes" was organized on the basis of Vinnytsia State Agricultural Institute. Leading experts in this field, noting the significant contribution to the school of Vibration Engineering under the leadership of P. S. Bernyk, proposed to create a professional all-Ukrainian scientific and technical journal "Vibration in engineering and technology..The journal was foundedat Vinnytsia State Agricultural Institute and P.S. Bernyk was elected to be the chief editor .
For all these years (since 1994) theJournal "vibration in engineering and technology" published 94 issues wherestudy of vibration effects, the creation of progressive energy saving technologies and equipment for their implementation were highlighted.
Currently Kaletnik H.M PhD , professor, academician NAAS is the chief editor of the "Vibrations in engineering and Technology"
The journal "Vibration in Engineering and technology", which has no analogues on the territory of Ukraine, is well known abroad.
