Published: December 2019

Abstract
The paper presents the results of plasma torch development and gas fluxes using possibility in plasma welding process. As part of the work, existing plasma torches were analyzed in order to identify opportunities for their modernization. The literature data was analyzed for identifying the optimal design of the plasma torch. During the study of literature data, it was found that the diameter of the nozzle tip has a great influence on the plasma welding process. Therefore, it was decided to model the processes occurring in the plasma torch using tips with different diameter sizes. Parameters that effects on the stability of plasma welding process were presented. Possible and potential effective plasma torch tip designs were proposed. The model of the behavior of argon in a plasma torch was constructed, which made it possible to draw conclusions about the optimum diameter of the plasma torch tip. Also, was shown the effect of the diameter of the plasma torch on the behavior of plasma gas.
Influence of the cross-sectional area of the shear layer on the distribution of the zones of tension and compression in replaceable cutting inserts
Authors: Kireev V.V. 
Published: December 2019

Abstract
As a result of the conducted researches it is established that with a progressive cutting scheme, the dangerous tensile stresses in the cutting carbide plates are significantly reduced. It was found that when using a worm cutter with a progressive cutting circuit, the dangerous tension of the tensile stresses on the front surface of the carbide plates is greatly reduced. Analysis of the obtained main stresses in the cutting wedge showed that the cutting edge experiences tensile stresses on the front surface, and compression on the front surface. It is established that the cutting element of the milling cutter undergoes an alternating asymmetrical nature of loading, accumulating cyclic fatigue in the main cutting edge.

Authors: Anikeeva O.V. , Ivakhnenko A.G. 
Published: December 2019

Abstract
The paper is devoted to the topical issue of the formation of a variation method for calculating the accuracy of metal cutting systems. The current state of the basic variation method for calculating the geometric accuracy of metal cutting machines is determined. A transition from considering the geometric accuracy of only the metal cutting machine to considering the accuracy of the metal cutting system is made, which includes the metal cutting tool. The proposed directions for the development of the method are recommended to be divided into groups according to the criterion of linearized and non-linear formulation when building accuracy balances. The solution of the problem posed in the paper serves as a methodological basis for work on normalization and compensation of geometrical errors of machine tools, including the creation of the foundations of standards for the accuracy of metal-cutting machines and tools. This work is useful for scientists engaged in the study of the geometric accuracy of processing on metal-cutting machines, as well as the normalization and compensation of the geometric errors of machines.

The nature of the metal-ligand chemical bond and the electronic structure of Be, Mg, and Zn acetylacetonates and hetero- and β-substituted analogs
Authors: Komissarov A , Shcheka O , Korochentsev V , Vovna V 
Published: December 2019

Abstract
The effect of valence molecular orbitals on the nature of the chemical bond of the p-metal ion with chelate ligands in Be(acac)2, Mg(acac)2 and zinc Zn(acac)2 was studied by theoretical methods. The effect of the substitution of atoms and functional groups in the ligands on the chemical bond was estimated. For beryllium, the bond is almost completely covalent with an insignificant ion component: the Coulomb potentials for complexes with beryllium are 1.37 and 1.08 eV for acetylacetonate and hexafluoroacetylacetonate, respectively. For Mg and Zn β-diketonates with a metal-oxygen bond, the calculations showed the essentially ionic nature of binding: about 8 eV for magnesium compounds and 12.3 and 11.3 eV for zinc. However, the O→S substitution significantly reduces the metal-ligand binding iconicity: to 2.8 and 0.9 eV for the thio- and dithio-substitution, respectively. The covalent bond of a metal with ligands is due to the overlapping of only some MOs with s- and p-orbitals of the metal. The covalence of the M–O bond in acetylacetonates decreases in the series Be→Mg→Zn due to an increase in the ionic radius of the metal, leading to two consequences.

Using fuzzy binary relations to characterize total power-load curve
Authors: Malafeev A.V. 
Published: December 2019

Abstract
The paper proposes an approach to load forecasting on the shop floor level of power distribution, as well as to forecasting the loads of process-sharing subdivisions for the dispatching of industrial pow-er supply. The approach implies mathematical representation of process linkages inside a production fa-cility as fuzzy relations. Fuzzy relations are described quantitatively by the incidence matrices, which are decomposed on multiple levels depending on the desired accuracy. It is proposed to find the coor-dinates of an ordered resulting curve, from which a daily curve can be derived on the known-form ba-sis. The approach can be used by the parameter and production teams of the Chief Power Engineer’s office of an industrial enterprise to make day-ahead curves as well as standard long-term daily curve.

Published: December 2019

Abstract
The paper presents an algorithm for optimizing the conditions of industrial thermal power plants in terms of repairs to their boiler units and turbine generators, which allows to determine the optimal composition of equipment removed for repair, taking into account the fuel used and the season. The algorithm is based on the dynamic programming method, which allows to set models of turbogenerators and boiler units in tabular form, which, when forming the equivalent characteristics of generators or boilers, allows simultaneous determination of the optimal condition of all equipment for a given electrical and / or thermal load of the power plant. The optimality criterion is the minimum of the total cost of the fresh steam needed to generate heat and power. The optimization algorithm and equipment models are specially adapted to the conditions of industrial power plants.

Authors: Kozlovsky V , Panyukov D , Ermakov V , Kolesov S , Kovaleva T 
Published: December 2019

Abstract
The causes of technological errors are quite numerous and varied, and they can be classified according to various criteria, for example, by the type of technological operations (errors in the machining operation of parts, winding and laying the windings into stator’s slots, etc.). The program performs an automated calculation of the characteristics of the generator when the input dimensional parameters of the core change within the limits of the tolerance field for each of them set by the technical specifications (TS). The algorithm of the program is based on the method of calculating a three-phase synchronous generator with a cranked rotor. To assess this effect, a system of interconnected computer programs and mathematical models has been built, with which it is possible to determine the weight of the influence of technological deviations in the manufacture of the generator on its performance and the characteristics of the electrical system as a whole. Reducing the variation of the generator reliability indicators can be achieved by phased assessment and timely adjustment of the quality level of design, production and ensuring their connection with the quality management system.

Improvement of the competitive edge of precast reinforced concrete is necessary to achieve due to the high quality and level of reliability. Previously, it can be concluded that there is significant potential to increase the level of reliability of precast structures by improving the quality of concrete and control. The advantages of precast concrete were considered in the paper. Changes of requirements of modern standards to the quality indicators of concrete strength including coefficient of variation of concrete strength properties were analysed. Assessment of the influence of the stability of precast reinforced concrete structures production due to such quality indicators as the coefficient of variation of the concrete strength and the accuracy of the cross section of precast elements was performed. The estimation of the variation coefficient of concrete strength from 9 to 13% in accordance with the changes in the modern regulatory documents was carried out in the paper. The results of the calculations show that the decrease of the reliability level takes place up to 30%.

Authors: Russkih I V 
Published: December 2019

Abstract
The article is devoted to the description of the application of a systems approach with the aim of improving the process of setting-up the equipment of cable manufacturing, namely, the extrusion line. First, a risk-based approach was used to identify the bottlenecks of the setting-up process using the FMEA methodology. Secondly, the most critical operations of the setting-up process were considered in terms of measurement authenticity. In this context, the analysis of the stability of the measuring process, an analysis of the bias linearity and an analysis of repeatability and reproducibility were carried out. Using the measurement system analysis, it was managed to reveal four main factors influencing the variation of the measuring process and recommendations were made to improve each of them. Corrective actions have been developed, after the implementation of which the level of general repeatability and reproducibility of the measurement process has passed into the category of acceptable. Thus, applying the principles of a systematic approach and using the tools recommended by IATF 16949 “Measurement system analysis” and “Potential failure mode and effects analysis”, we managed to achieve a new level of quality of the process setting-up an cable manufacturing, reduce the risk level of the process and minimize costs.

Abstract
Educational organizations in modern society are full participants in economic activity, they also face various “threats” that affect the quality of their work. The consequences of these threats can be of different levels: as insignificant as well as before the devastating scale that can lead institutions to the partial or complete failure of the educational system. These risks can be located both inside and outside the organization. It is very important to realize that managing risks is possible only when they are known, otherwise it is simply not feasible. To be competitive in the developing area of education it is necessary to identify threats timely, to assess them directly and adopt any management decisions. It is a necessary measure to reduce risk. Such systematic risk management will allow higher education institutions to provide high quality education on their academic programs.
