“…In the experiments, the supply in turning the blanks is 0.20 mm/turn. As we know [3,6], the longitudinal supply has a considerable influence on the geometric parameters of the machined surface of the polymer blank. The influence of the supply on the hardness of the blank's machined surface is of practical interest.…”

“…Polymer crystallization increases the hardness, elastic modulus, strength, and other mechanical characteristics, since the hardness, strength, and density of crystallized polymer are higher than for amorphous polymer. Thus, taking account of the elastoplastic deformation of the machined material in the cutting zone [6], we may conclude that the cutting of caprolon and fluoroplastic is accompanied by recrystallization and hardening of the surface layer on account of increase in the content of crystalline phase.…”

The paper presents the results of experimental studies to determine the hardness of the treated surface depending on the conditions and machining type of workpieces made of textolite, caprolon and fluoroplastic. The experimental methodology and explanation of the reasons for changing the hardness of the treated surface for the investigated variants of machining the materials are under study. The results of studying the influence of the phenomenon of elastic aftereffect of the polymer materials after workpieces machining are obtained.

“…Понятие совместимости для ЭП имеет сложную иерархическую структуру. Требования к совместимости должны быть выполнены как в отношении простейших элементов ЭП (электродвигателя, устройства преобразования, управления и передачи), что в результате обеспечит согласование моментов и скорости двигателя с усилиями и скоростью исполнительного органа технологической машины, так и в отношении сложных технических систем (ТС), включающих в свою структуру подсистему ЭП для обеспечения совокупности свойств, определяющих их функциональное назначение [9,10].…”

The article provides methods for assessing the compatibility of elements in the design of complex technical systems. The compatibility of the elements is considered as the main indicator that determines the quality of systems including heterogeneous elements. The presented methods make it possible at the design stage to choose a technical solution that is most suitable for the project objectives, taking into account the operating conditions of the system. The methods make it possible to evaluate compatibility by a single and complex indicator. The choice of indicator depends on the purpose of the assessment. An example of methods implementation in the design of systems including an electric drive and pipeline shutoff valves is considered. It has been experimentally proved that in systems with low values of the compatibility level, the actual power characteristics exceed the required values, which leads to additional voltages in the system elements and their breakdowns. The results of the assessment of typical systems allowed to identify the shortcomings of existing structures and propose alternative solutions to problems. The compatibility of elements within the framework of a technical system makes it possible to increase the functional efficiency of systems with minimum weight and size and power characteristics, to optimize the price-quality ratio, and to increase the competitiveness of the final product.
