Volume 1 N2 - Unsteady turbulent flows with solid particles of different sizes in the cyclone were studied numerically and experimentally. The grid studies and influence of the boundary condition prescription on the flow behavior in the cyclone and the effectiveness of the particle separation were studied firstly numerically. The turbulent flow was calculated by means of Large Eddy Simulations and this flow problem was calculated parallel using eight processors. It was found theoretically that pressure at the bottom outlet of the cyclone has a significant impact on the particle separation. This impact of the pressure at the cyclone function was examined also using experiments and pressure distributions for different flow rate intensities for several locations in the cyclone were determined. These experimental results can be used for a validation of numerical results. Furthermore, the larger losses were observed in the immersion tube due to higher flow velocity and impulse exchange in the vortex core.

The dimensions were also measured using two-dimensional (2D) sections of the scanned samples. It has been determined that the clean waterjet cutting tends to separate soft materials such as plastic, foil, foam or paper, as well as food. Unlike the pure waterjet cutting, the abrasive cutting is used for hard materials such as steel, ceramics, glass. The optimal pressure for material processing has been calculated. Particular emphasis is placed on the separation of composite materials, which cannot be satisfactorily accomplished using conventional methods. N2 - В статье приведены результаты исследования производственных допусков при водоструйной резке методом трехмерных (3D) измерений: отклонения формы были показаны путем трехмерного справнения отсканированных образцов. Размеры были измерены также с использованием двухмерных (2D) срезов отсканированных образцов. Определено, что чистая водоструйная резка имеет тенденцию отделять мягкие материалы, такие как пластмасса, фольга, пена или бумага, а также пища. В отличие от чистой водоструйной резки, абразивная резка используется для твердых материалов, таких как сталь, керамика, стекло. Вычислено оптимальное давление для обработки материалов. Особое значение уделено разделению композитных материалов, которое не может быть удовлетворительно осуществлено с использованием обычных методов.

The results are also displayed in Excel using a number of cutting parameters. For this purpose, the article shows the results of both high-speed milling and high-speed turning of a machine with different types of tools, as well as processing of one tool on different types of machines. Unlike other machines, in general, the work on the machines of universal processing centers turned out to be more productive. The feed rate of the machine tools is the focus area here. If we increase cutting values, then the tool life is reduced and that leads to higher tool costs. With universal high-performance machines we cannot save costs for tools (we can only save machine tool costs). Compared to universal high-performance machines, we can save tool costs with Universal Machining Center. Therefore, it is suggested to the machining with the universal machining center, although the machining time and cutting time is faster with the universal high-performance machine. N2 - В статье показаны результаты как высокоскоростной фрезерной, так и высокоскоростной токарной обработки станка с разными типами инструментов, а также обработки одного инструмента на разных типах станков. В отличие от других станков, работа на станках универсальных обрабатывающих центров оказалась более производительной. В центре внимания здесь скорости подачи станков. Если мы увеличиваем параметры резания, то срок службы инструмента снижается, что приводит к увеличению затрат на инструмент. С универсальными высокопроизводительными станками мы не можем сэкономить на инструментах (мы можем сэкономить только на станках). По сравнению с универсальными высокопроизводительными станками, мы можем сэкономить на инструментальных средствах с помощью универсального обрабатывающего центра. Поэтому рекомендуется выполнять обработку на универсальном обрабатывающем центре, хотя время обработки и время резки меньше на универсальном высокопроизводительном станке.

Thus, the physical essence of waterjet processing is that the cutting process is carried out by removing chips from the surface of materials using a jet of water and abrasive grains supplied to the cutting zone under high pressure.

Their advantage over universal lathes lies not only in the high accuracy, but also in the ability to machine complex parts and automate the working process. The paper considers possibility of reaching high precision in machining the stepped shafts of a 10-ton overhead crane on the lathes. Based on design and technological computation, it was difficult to achieve the required accuracy and roughness of the machined surface in machining a stepped shaft of the overhead crane on a universal lathe. Using the CNC lathe eliminated many of the disadvantages of the step shaft finishing lathing. The paper shows that accuracy of the stepped shaft finishing on a CNC lathe is significantly influenced by the cutting mode parameters. Studies were performed making it possible to determine those parameters values that ensured the highest accuracy in the stepped shaft manufacture.

It has been determined that during processing shafts on a CNC lathe, the maximum deformation is observed near the tailstock side of the machine.

МАШИНОСТРОЕНИЕ N2 - Разработка технологии механической обработки восстанавливаемых в ремонтном производстве деталей, включающая в себя выбор способа и режимов их обработки, режущего инструмента и др., является сложной задачей, решение которой определяет качество восстанавливаемых изделий. Качество механической обработки во многом зависит от обрабатываемости металла, под которой понимают способность материала подвергаться резанию. Рассмотрены особенности механической обработки втулок по- сле восстановления изношенной внутренней поверхности, состоящей из черного, чи- стового и тонкого растачивания, а также операции хонингования. При механической обработке восстанавливаемых втулок наибольшую трудность представляют операции чернового и чистового растачивания, так как после индукционного напекания с по- следующим раскатыванием твердость получаемых слоев находится в пределах HRC 48…55, что усложняет работу резцов при растачивании втулок. Для наплавки на де- тали, работающие в условиях изнашивания (коррозионного, эрозионного и термиче- ского), применяют порошок ПГ-СР2, имеющий систему легирования Ni–Cr–B–Si. Значительную волнистость и шероховатость поверхности, возникающую в результате наплавки, устраняют накатыванием. Одним из важных вопросов при обработке по- крытий, нанесенных центробежным индукционным напеканием с последующим рас- катыванием, является выбор материала и геометрических параметров режущего ин- струмента для чернового и чистового растачивания. При правильном выборе матери- ала и геометрических параметров расточного резца можно значительно уменьшить износ режущего инструмента, что позволит увеличить его стойкость и производи- тельность обработки, а следовательно, снизить себестоимость изготовления детали. Исследовано влияние технологических параметров на износ и геометрических пара- метров на стойкость режущего инструмента с целью оптимизации условий растачи- вания восстановленных цилиндров судовых двигателей. N2 - Design and development of a technology for machining the parts to be restored in the repair industry includes selection of their machining method and modes, cutting tools, etc., and is a complex task, which solution determines the restored product quality. Machining quality largely depends on the metal machinability, which is understood as the material ability to be cut. The paper considers features of a bush machining after restoration of the worn inner surface, this operation consists of black, clean and fine boring, as well as of honing. Opera- tions of black and clean boring are the most difficult in machining the restored bushes. This happens because hardness of the resulting layers is in the range of HRC 48…55 after induc- tion sintering with subsequent rolling, which complicates the cutters operation in bush bor- ing. The PG-SR2 powder having the Ni-Cr-B-Si alloying system is used in the built-up weld- ing of parts working under wear, corrosion, erosion and elevated temperature conditions. Rolling is eliminating significant waviness and surface roughness resulting from sintering. One of the important issues in machining the coatings applied by centrifugal induction sin- tering is selection of the cutting tool material for black and clean boring.

МАШИНОСТРОЕНИЕ N2 - Распределение температуры во втулке цилиндра судового двигателя при ее нагреве и охлаждении — один из важнейших факторов, под действием которых формируются структура и свойства покрытий в процессе восстановления цилиндра методом центро- бежного индукционного напекания. Проведены экспериментальные исследования, позволившие получить графики распределения температуры по диаметрам втулки ци- линдра судового двигателя при ее нагреве и охлаждении. Установлено, что на процесс напекания порошковых материалов существенно влияют теплофизические свойства втулки. Изменяя скорость нагрева, можно получать покрытия при различных значени- ях температуры и времени напекания. Выполнено моделирование распределения тем- пературы в стенке втулки цилиндра при центробежном индукционном напекании в за- висимости от времени напекания, а также с учетом геометрических параметров втулки, теплоотдачи, теплопроводности, материала втулки, температуры внешней среды и т. д.

N2 - The temperature distribution in the ship engine cylinder sleeve during its heating and cooling is one of the most important factors affecting formation of the structure and properties of coatings in the process of cylinder recovery by the method of induction centrifugal sintering. The article discusses experimental studies, which allow presenting graphs of the temperature distribution over the diameters of the ship engine cylinder sleeve during its heating and cool- ing. The thermophysical properties of the sleeve were found to significantly affect the process of sintering powder materials. By varying the heating rate, it is possible to obtain coatings at different temperatures and sintering time. Modeling the temperature distribution in the wall of the cylinder sleeve during centrifugal induction sintering depending on the sintering time is of interest as well as taking into account the geometrical parameters of the sleeve, heat trans- fer, thermal conductivity, sleeve material, ambient temperature, etc. Expressions are obtained for determining the temperature distribution in the wall of the cylinder sleeve during induc- tion centrifugal sintering. Using the obtained formulas, it is possible to simulate and obtain in advance the temperature distribution in the wall of the cylinder sleeve by setting the values of the parameters of centrifugal induction sintering. Modeling in the Autodesk Fusion 360 the temperature distribution in the sleeve during induction heating was obtained as well as visual display of the change in the temperature field in the sleeve during induction heating.
