Purpose: This article is devoted to the development and mathematical modeling of the new technology of forging of blanks such as slabs and plates from ferrous and non-ferrous metals and alloys in a step dies with a wedge bumps and hollows, allowing for minor energy consumption to intensify shear deformation in both longitudinal and transverse directions. Design/methodology/approach: The combination of two designs of dies will allow with minor inputs to intensify the shear deformation, in both longitudinal and transverse directions. Findings: When its use the optimal and uniform distribution of the stress state is realizing, adequately implemented deforming, especially in the axial zone, as well as significantly less deformation load compared to the flat step dies. The use of a step-wedge dies during deformation will produce blanks with the qualitative deforming of the structure throughout the cross-section with little energy consumption. Researches limitations/implications: During the simulations were studied energy-power parameters and stress-strain state of workpiece under its deformation in dies of new design in comparison with forging of similar workpieces in a normal step dies and ordinary wedge dies. Originality/value: Wide development must receive an engineering service, as a basis for a knowledge-based economy. One of the main directions of implementation of this strategy is the construction of new and modernization of old enterprises for processing of ferrous and non-ferrous metals and alloys by pressure treatment that will produce competitive products not only on the domestic market, but also on international.
