The purpose of modeling is the analysis of the stress-strain (VAT) [7,14] condition and deformation of tubular, cylindrical workpieces in the deformation process, determining the energy parameters of the process, as well as the geometry of the deforming tool. transverse and longitudinal directions, as well as the cleanliness of the surface of the profiled cavity.

This article analyzes the features of local deformation, which define stamping by rolling as an independent type of metal pressure treatment in the metalworking industry. This problem is most effectively solved by using cold plastic deformation processes, which allow to bring the shape of the workpiece as close as possible to the shape of the finished product, and in some cases eliminate the need for further processing. Using the method of cold deformation instead of cutting, you can increase 2… 3 times the utilization of the metal. This ensures high quality of the workpiece surface, improves the physical and mechanical characteristics of the material, increases productivity and creates conditions for full automation of production. Examples of the most complete realization of advantages of stamping by rolling that provides efficiency of industrial use are resulted. In the priority areas of science and technology, a special role is given to energy and resource conservation.

In [3] the simulation results for rolling stamping without restriction with one-sided and two-sided restriction of metal flow along the length of lead blanks are presented.

 Analysis of the experimental study showed that the process of stamping rolling (SHO) workpieces with conical and cylindrical rolls, allows you to control the flow of workpiece material by changing the size and direction of the axes of the workpiece roll, relative to the direction of rotation of the workpiece. The conducted modeling of SHO processes showed that the stress-strain state, deformation and deformability of the workpiece material also significantly depend on these parameters.

The technological capabilities of the SHO are limited mainly by the loss of stability and destruction of the workpieces, which, in turn, significantly depends on the direction of flow of metal at the contact of the roll with the workpiece.

Thus, the ability to control the direction of flow of the metal largely determines the ability to manufacture workpieces of the desired shape and size without destruction and loss of stability [2].

History of journal:

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.
