The article conducted a study of calculation methods and the selection of technological parameters for stamping by rolling in complex profile products. It is shown that the achievement of significant sizes of various elements of the workpiece is possible by ensuring the directional flow of metal by changing the relative positions of the roll and the workpiece. The most effective rolling stamping operations are upsetting, deposition and backward extrusion. The zones of workpieces that are deformed under stress conditions have been identified, therefore, to determine the technological capabilities for them, an assessment of the deformation of metals should be carried out. The manufacture of thin-walled elements of the workpiece using the operation of backward extrusion is accompanied by the appearance of significant contact stresses, therefore, to prevent the roll from being removed from the workpiece, back-up rollers should be provided.
The analysis of the study showed that the stamping process by rolling over the workpieces with conical and cylindrical rolls makes it possible to control the flow direction of the workpiece material by changing the size and direction of the relative position of the axes of the workpiece roll, relative to the direction of rotation of the workpiece. The technological capabilities of SHO are limited mainly by the loss of stability and destruction of the workpieces, which, in turn, substantially depends on the direction of the metal flow in the contact of the roll with the workpiece.
The modeling of the SHO process is considered. It has shown that the stress-strain state, the shape change and the deformability of the workpiece material substantially depend on these parameters.
The purpose of the simulation was to analyze the stress-strain (VAT) state and shape change of the workpieces during the deformation process, to determine the energy-power parameters of the process, as well as the geometry of the deforming tool, providing a high-quality product with guaranteed profile filling, accurate dimensions in the transverse and longitudinal directions, as well as surface cleanliness profiled cavity.

Technology, energy, agriculture transport AIC is a scholarly professional journal with a long-standing history and stable academic tradition, reflecting the evolution of engineering and technical sciences within the agro-industrial sector of Ukraine.
The journal was founded in 1997 under the title Bulletin of Vinnytsia State Agricultural Institute. According to the Resolution of the Presidium of the Higher Attestation Commission of Ukraine dated September 11, 1997, the publication obtained the status of a professional scientific journal, which enabled the publication of the main results of doctoral and candidate dissertations in technical sciences. From its inception, the journal positioned itself as an academic platform for addressing current issues of mechanization, electrification, and technical support of agricultural production.
During 2001–2014, the journal was published under the title Proceedings of Vinnytsia National Agrarian University. Series: Technical Sciences (State Registration Certificate of Print Media KV No. 16644-5116 PR dated April 30, 2010). Throughout this period, a systematic approach to the selection and peer review of scientific manuscripts was established, the thematic scope of publications was expanded, and continuity of scientific directions as well as the development of sectoral engineering schools was ensured.
Since 2015, the journal has been published under its current title, Technology, energy, agriculture transport AIC (State Registration Certificate No. 21906-11806 R dated March 12, 2016). The change of title reflected the expansion of the journal’s thematic coverage and its orientation toward interdisciplinary research in mechanical engineering, energy systems, electrical engineering, transport technologies, automation, and digital solutions for the agro-industrial complex.
The journal consistently adheres to the principles of open science. All published materials are distributed under the Creative Commons Attribution 4.0 International License (CC BY 4.0), ensuring open access to research results provided proper attribution to the authors and the original publication is maintained.
At present, Technology, energy, agriculture transport AIC is an authoritative professional scientific journal (Category B), providing a platform for the publication of fundamental and applied research results, promoting the integration of education, science, and industry, and contributing to the advancement of engineering and technological support of the agro-industrial complex of Ukraine.
