The article presents the results of development and research of technological schemes of cold forming by rolling (CFR) of blanks. Expansion of the technological capabilities of the processes of COP and improving the quality of products is based on the control of active friction forces and deformability of the processed metals. The main limiting factors in the application of SHO processes are insufficient ductility of metals, which causes the risk of destruction of workpieces, as well as relatively large deformation forces that cause unfavorable operating conditions of the rolling bearing unit. The solution of these problems is facilitated by the transition to hot SHO. However, the problems of manufacturing by the hot SHO method of products from tubular and solid cylindrical billets have been little studied to date. An effective process of billets heating is induction heating, but its application is characterized by relatively low efficiency.
In this work, it is recommended to use new materials and technology for the manufacture of induction heaters for the implementation of hot SHO, which open up opportunities for improving induction heating equipment for industrial applications. The use of new generation induction heaters to replace other heating methods in metalworking has significant advantages: higher efficiency; less scattered magnetic fields; less complexity of the coil design; increased geometric freedom; no water cooling is required.
In order to study the hot SHO, devices for rolling billets with conical and cylindrical rolls were designed and manufactured. Physical modeling of hot SHO by using solid cylindrical lead billets was carried out. It is experimentally proved that the process of hot SHO allows to achieve significant degrees of deformation even at unfavorable stress-strain state and insignificant power of the equipment. Thus, the process of induction heating of blanks can be quite effective when processing them by hot SHO.

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 119 issues wherestudy of vibration effects, the creation of progressive energy saving technologies and equipment for their implementation were highlighted.
Currently Ihor Kupchuk, Candidate of Technical Sciences, Associate professor, Associate Professor of the Department of Engineering Mechanics and Technological Processes in the Agricultural Industry Faculty of Engineering and Technology Vinnytsia National Agrarian University is the chief editor of the "Vibrations in engineering and Technology"
