The research was conducted at the Department of Aircraft Technology and Design of the Educational and Research Institute of Mechanical Engineering of the National Technical University of Ukraine “Igor Sikorsky Kyiv Polytechnic Institute”. On the basis of performance of scientific subjects concerning compression of a tubular cavity preparation with formation of an internal cavity the most perspective schemes of such technological processing were investigated and technological and constructive elements of processes and the equipment were defined. Indicators such as quality (compliance of the product with the requirements of use) and its cost, process productivity, technical and economic characteristics and versatility of the equipment were taken into account. To experimentally confirm the chosen direction of implementation, first of all, experimental equipment was designed and the technical process was modeled according to each of the proposed schemes.

The article proposes a scheme of the process of manufacturing bimetallic tubular elements by extraction a cylindrical cup of two dissimilar metals without thinning and extraction with thinning cup. At the same time, in the process of extraction in the heated state, the layers of dissimilar metals and alloys are connected and the desired shape of the product is obtained. A mathematical model of deformation of the process of joint extraction with thinning of two dissimilar metals with heating in a flat deformed state is developed. The influence of the deformation value on the dispersion of mechanical energy by bimetal was revealed.
