Purpose of work - development is scientific technological base for perfection of processes and equipment for treatment of metals by pressure, upgrading metal products and decline materials and energy intensity of production. A research method is methods of experimental and theoretical research of processes and equipment for treatment of metals by pressure. In the presented work the method of cylindrical sections is utillized for an analysis tensely deformed state in the open frames of crank-presses. As a result of mathematical modeling, presented that the contour of sheet at all stages of the supperplasticity forming can be described with universal formulas which are known as a "superformula" of Dzhilisa or "superellipse" of Lyame. Based on the improved calculation methodology, axial force distributions are obtained depending on different technological factors for cold sheet rolling. On the basis of method of eventual elements it is rotined distribution deformations of layers of bi metallic sheet.The method of increase of efficiency of technological butters and equipment is in-process presented for his realization. On the basis of method of eventual elements dependence of effort of deformation is considered on relative deformation at broaching by the instrument of different configuration and with different correlation of diameters of purveyance and diameters of ledge on the profiled fellings. With the use of method of sliding lines the analysis of the tensely deformed state of metal and character of distributing of tensions is conducted in the cell of deformation at cuting.
