World trends and prospects of development of technological equipment complexes are considered. The applied stages and phases of machining equipment design are analyzed by means of constructing design ...schemes traditional for machine mechanics. It is proposed to create technological machine tool complexes by layout synthesis with the help of element base, which should contain functional technological and service modules, and the service purpose of the machine tool should include the nomenclature of manufactured surface modules. It is shown that the prospects of application of energy flows for intensification of machining processes should be analyzed at the early stages of design, using thermal and electrophysical criteria to study the emerging relations in the system. It is suggested to start designing mechatronic systems of machine tool complexes from the analysis of structural relations of information technologies in hybrid production including traditional and additive technologies.
The analysis of design stages of technological equipment for traditional production is carried out, the features of the formation of technological equipment are studied using flows of energy and ...consumables. Structural synthesis of mechatronic complexes in digitalized production made it possible to add new stages to the process of creating technological equipment for both traditional automated subtractive manufacturing and new additive manufacturing. The processes of manufacturing parts without shape-generating molding tools, described by the algorithms according to the proposed structural diagram of connections, provide an opportunity to analyze existing and develop new methods of laminate synthesis of products. It is shown, how in the design of technological equipment for their use in new additive and traditional subtractive manufacturing, methods and schemes of laminate synthesis and shaping of parts from composite materials are used, based on the application of various energy flows and material components, as well as methods and schemes of automation and computer product manufacturing process management.
The disadvantages of the traditional description of a mechanical engineering product are considered, which are based on features focused on single, typical and group operations of the technological ...process. It is proposed to design and manufacture individual elements of parts and the product as a whole from the standpoint of operation and monitoring of its condition using the modular approach in engineering and technology. The representation of parts by sets of modules makes it possible to identify the locating, working and binding modules of the surfaces and on their basis to build a unified classification of parts focused on various stages of the product life cycle. The fundamentals of the locating theory are updated, taking into account the revision of the existing description from theoretical mechanics by means of the position of 3 coordinate points; for the transition to a new description from the theory of machines and mechanisms by depriving of object of locating the degrees of freedom (mobility) in the technical system (design, technological, measuring one). It is shown how the design of the production technology of the product and the measurement of its characteristics is carried out in a system that includes equipment and facilities as mechanisms, the closing link of which are locating items.
The stages of the development of the physicochemical foundations of materials science are revealed, and the state and prospects of the development of nanostructured material science based on a ...comprehensive study of the structure of matter at various scale levels are determined. The use of complex analysis of the formation of material structures is characterized by traditional for chemistry and physics study of the balance of matter and energy flows, supplemented by an analysis of entropy formation and by physical and chemical analysis of combinatorial topology used to describe non-equilibrium phase transitions as well as by based on the synergetic approach percolation representations of fractal geometry, used to describe a complex of structures. It is shown that for the study of non-equilibrium processes of synthesis and application of micro- and nanostructured materials it is expedient to supplement the principles of physicochemical analysis: continuity principle — by considering additionally energy dissipation in the formation of structures and phases; correspondence principle — by fractal representations of geometric images; compatibility principle — by the study of possible ways of evolution of the system. This allows quantitative analyzing of transient processes described by non-integer values of the degrees of freedom of the system and the emerging structures with multi-fractal phase parameters.
The reasons for the divergence between the calculated results of the height of the microasperities of the kinematic and geometric representations of the formation of the surface with the edge tool ...and their values obtained during machining are studied. The analysis of the formation of microasperities in the area of chip formation is made, and the mechanism of increment of their height is considered, due to the fact that not all of the processed material allowance is removed during cutting. Most of the material is removed in the form of chips, and a smaller part of it flows around the back surface of the tool and pressed out into the top of the asperity. The promissing directions of microasperities height control on the treated surface are determined, and it is proposed to develop and apply tools that reduce the value of the end cutting edge angle and increase the radius at the top, as well as tools that minimize plastic deformation of the treated material in front of the front surface. The complex of studies on the processing of parts from materials with heterogeneous structure showed that the features of the structure limit the possibility of technological quality control of the treated surface of products.
