“…The design layout is formed according to the principles outlined directly for a specific type of equipment. Based on the data sheet (from the technical passport of equipment), which can be presented in QR code format, the designer selects and reserves technological modules that can implement the proposed technological layout (which greatly simplifies the design process) and designs the original systems and elements of the machine that are necessary for its normal operation (mounting and clamping fixture [29][30], spindle groups [19], conveying systems [31,32], etc.). The application of modern CAD/CAM systems allows to accelerate of the process of layout design and simulation of machining, verify the performance and output characteristics of equipment, and, consequently, to verify the provision of the specified parameters of the processed product, specify the design parameters, if necessary.…”

The article analyses a wide range of existing technological systems for machining engineering production from special aggregate machines with rigid kinematic connection (control system) to portable machines with mechanisms of parallel structure, which are based on the aggregate-modular principle of the layout. The advantages and disadvantages of such equipment in the modern conditions of manufacturing development are considered in terms of their life cycle in the supply chain and the prospects for further implementation in the machine tool market. The authors analyze the contradictions between the performance and technological flexibility of machining systems and propose ways of resolving these contradictions on the basis of scientific achievements in the field of components, mechatronics, and CALS technologies. On the basis of the performed analysis, the authors suggest a concept and partially implemented a technique for creating various purpose machine-tool systems based on unified technological mechatronic modules considering the tendencies of modern machine-tool production to ensure the sustainability of enterprises under conditions of rapidly changing demand. The prospects of using augmented reality (AG) manufacturing tools for passportization of equipment and its components in order to optimize and green the life cycle of metal-cutting equipment have been substantiated.

“…The formation of surfaces of thin-walled parts with variable low stiffness requires a consideration of a number of factors that could prevent the achievement of technological requirements for the product [6,7]. Such factors are: deviations from a given shape that increases during processing, vibrations, thermal deformations and errors caused by tools, tool-path accuracy, technological equipment [8,9] and fixtures [10,11].…”

The disadvantage of the geometry of thin-walled parts, in terms of processing, is the low ability to resist static and dynamic loads. It is caused by the elastic deformation of elements with a low stiffness. Modelling approaches for the evaluation of deflections during machining are presented. Mathematical models of deflections, cutting forces and harmonic response are proposed. The processes of material removal and deflection of a thin-walled sample at the critical points are modelled. A frequency analysis was performed, consisting of a modal analysis of natural frequencies and a harmonic response analysis. As a result, a graph of the deflections amplitude from the frequency of driven harmonic oscillations is generated. The analysis of the obtained values was performed. As a result, the resonance frequency and maximum amplitude of oscillations for the operating parameters are determined.

“…In materials science, studying the vibrational impact on irregularities of surfaces [19] and tribologically testing impulse systems [20,21] are urgent problems. In manufacturing engineering, the problem of ensuring the vibration reliability of fixtures [22] is significant. Consequently, spectral analysis of the experimentally obtained signals is mandatory.…”

This article is devoted to the problem of signal decomposition into periodic and aperiodic components. According to the proposed approach, there is no need to evaluate the aperiodic component as a difference between the total signal of its periodic components. This research aims to create a general analytical approach that combines the Fourier and Maclaurin series methodologies into a single comprehensive series. As a result, analytical expressions for determining deposition coefficients were established for an aperiodic signal with a monoharmonic overlay. Recurrence relations were established to determine the coefficients of this series. These relations allow direct integrations of the obtained values of integrals to be avoided. The evaluated numerical values of the coefficients are also presented graphically and tabulated. It was proven that the values of these coefficients are universal numbers since they do not depend on the period/frequency of oscillations. The reliability of the proposed approach was confirmed by the fact that the evaluated coefficients are equal to the Fourier series coefficients in the case of a periodic signal. Also, for an aperiodic signal, these coefficients were reduced to the coefficients of the Maclaurin series. The usability of the proposed generalized analytical approach for signal decomposition is for control and monitoring systems of processes.
