Technology Typification, Technological Development Modes and Sovereignty Assurance DOI: 10.22184/2499-9407.2024.37.4.24.30
The paper considers the taxonomy of technologies used in the economic analysis of technological evolution, as well as the modes of technological renewal according to the principles of “creative destruction” and “combinatorial build-up”. A general assessment of the achievement of the goal of ensuring of technological sovereignty of Russian Federation is given.

Expanding the use of cold-extrusion stamping by developing presses that create actively directed contact friction forces DOI: 10.22184/2499-9407.2024.37.4.48.54
The high-performance technology of cold extrusion of workpieces makes it possible to produce parts with low surface roughness and a structure with increased strength without cutting subsequent and heat treatment. The scope of application of this technology is limited by high stresses in the punches deforming the workpieces, leading to insufficient fatigue resistance of the punches. Extrusion with actively directed contact friction forces, which contribute to the shaping of the workpiece, allows you to unload the punches and produce parts without using heating, even from low-alloy medium-carbon steels. For the implementation of such stamping requires the use of specialized presses is required, the designs of which are described in the paper.

Information and Technological Fundamentals of a Computed Design System of Multi–Level Basic Group Technology. Part II DOI: 10.22184/2499-9407.2024.37.4.56.63
The paper describes information and technological principles and methodology multitier basic technology system design, used top-down and bottom-up methods designing “analysis-synthesis” of construction-technological information. Application of the method of synthesis for solving the enumeration technically possible integrable transitions, and set the position on professional PCs with proper table-filling technology matrix of average skill enable optimal for the existing production group process of machining precision turned parts simple and complex shapes. The system allows you to formalize the decision-making process at the optimal level for the synthesis of group tool adjustments, selection of a unified tool model and cutting modes with a real forecast of cutter life. The advantages of the proposed approach compared to traditional ones are a significant increase in quality of the developed group technology and a sharp reduction in the time required for technological preparation of modern high-tech precision production.
