The character of the shape change is analyzed and the problem of determination of the stress-deformed state of the ring blank with a complex profile of the end part, which is obtained by direct extrusion with the use of the stamping process by means of melting, is solved. As the main methods of research, the method of dividing grids and the measurement of hardness, as well as the analysis of the microstructure of the material have been selected.
The picture of the distribution of the intensity of deformations and the stress state index in the cross sections of the cam half sleeve is obtained, as well as the ways of deforming the particles of the material of the most dangerous zones of the workpiece in the coordinates of the marked parameters. The ways of controlling the flow of material of a workpiece and estimation of its deformity are determined.

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.
