“…Executions of transversely fi nned surfaces differ in manufacturing technology and in geometric, mass, thermo-physical and thermo-aerodynamic parameters [7,8]. Cross-fi nned pipes are produced by the following methods: special casting methods [9][10][11], installing or rolling on alongside with brazing spiral-ribbon fi ns [12], pressing the fi ns along the guide [13,14], knurling bimetallic (aluminum and copper) fi ns on a steel supporting pipe [15][16][17], electric arc or high frequency currents (HFC) welding of fi ns [18]. In the case of cold knurling of fi nned surfaces, the axial, radial, and circumferential components of the cold knurling force have a signifi cant effect on the nature of the deformed metal fl ow.…”

Regulating the deformed metal's fl ow is an important condition for the knurling process. To achieve this, the knurling tool should have a special intake part, where all the main work of plastic deformation would be realized. Depending on the confi guration, the fi ns can be knurled in two ways: either by a radial feed of the tool or an axial feed of a billet (package of billets) or a tool. Using the radial feed method, most types of piece gear parts can be knurled using a more rational radial fl ow of the deformed metal. However, this process is usually characterized by low productivity. The axial knurling method is signifi cantly more productive. In this case, due to the undesirable axial fl ow of the deformed metal, it fl ows to the ends of the billets. As a result, it becomes necessary to introduce additional machining operations and metal waste increases. The article provides an analysis of existing methods of forming fi ns on a cylindrical surface. The authors analyze the advantages and disadvantages of applying the methods in modern conditions, select the most appropriate method, and substantiate the principles of developing tools for cold knurling of fi ns. The purpose of the work was to develop a tool for determining the forces acting in the cold knurling process and study their infl uence on the characteristics of the fi nal products.

To study the technological process of rolling solid and hollow round profiles, it is important to have a correct mathematical description of the patterns that determine the boundaries of the deformation zone. The article analyzed scientific works that examine the calculation of geometric parameters of the deformation zone during the rolling of solid and hollow round profiles in two-roll and multi-roll calibers. As a result of the analysis, a conclusion was drawn regarding the necessity of a more detailed description of the determination patterns for the geometric boundary conditions of the deformation zone. This led to the proposal of a universal method for determining the shape of the billet and the shape of the caliber groove, as well as the derivation of the equations for the roll surface and the boundary of the contact surface of the deformation zone for various rolling schemes. The developed method allows for an increase in the accuracy of calculating the energy-force parameters of the rolling processes, including continuous rolling, in the production of solid and hollow round profiles according to the circular–oval scheme in calibers formed by any number of rolls, thanks to the consideration of a sufficiently wide range of geometric features
