“…Despite the fact that threaded connections seem to be simple products, there is a lot of scientific work related to the problems that appear at different stages of their life cycle, in particular during the design, manufacture and operation [28][29][30][31][32]. Specifically for threaded connections of oil and gas equipment, such areas of research as analytical modeling [33][34][35], investigation of manufacturing errors [36][37][38] and corrosion fatigue [39][40][41] are important. Due to the prevalence of such products, we chose an educational PLMsystem for threaded connection for research.…”

The PLM concept implies the use of heterogeneous information resources at different stages of the product life cycle, the joint work of which allows you to effectively solve the problems of product quality and various costs. According to the principle of isomorphism of regularities of complex systems, an effective PLM system must have these regularities. Unfortunately, this principle is not often fundamental when designing PLM systems. The purpose of the work is to show, using a simple example, the principles of development, operation and use of an educational multi-agent PLM system, the main purpose of which is to study and research these regularities in the life cycle of a special threaded connection. The multi-agent approach to the development of a PLM system provides the necessary prerequisites for the emergence of system-wide regularities in it. The parallel work of agents is implemented using the actor model and the Ray Python-package. Agents for the logical inference of knowledge base facts, CAD/FEA/CAM/SCADA agents, agents for optimization by various methods, and other agents have been developed. Open source software was used to develop the system. Each agent has relatively simple behavior, implemented by its rule function, and can interact with other agents. The system can work in interactive mode with the user or in automatic mode according to a simple algorithm: the rule functions of all agents are executed until at least one of them returns a value other than None. Examples of the operation of the system are given and such system-wide regularities as emergence, historicity and self-organization are demonstrated in it.

“…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.

“…To increase their wear resistance, galvanic chromium plating [1], thermal spray coating [2][3][4], Plasma Electrolyte Oxidation (PEO) [5][6][7][8][9], and Hard Anodized Layer (HAL) formation [10][11][12] are most often used. The use of carcinogenic and environmentally harmful electrolytes in the implementation of the chromium plating method makes it environmentally hazardous [1,13,14]. PEO is used to form oxide layers on compact aluminum alloys [15][16][17], to oxidize aluminum coatings deposited in various ways on a steel base [18][19][20][21][22], or on other substrates [23,24].…”

The Effect of Heat Treatment on the Structural-Phase State and Abrasive Wear Resistance of a Hard-Anodized Layer on Aluminum Alloy 1011

The aim of this study was to evaluate the effect of heat treatment on the phase composition, hardness, and abrasion wear resistance of hard-anodized layers (HAL) on 1011 aluminum alloy. X-ray diffraction analysis revealed the Al2O3·3H2O phase in the structure of HAL synthesized for 1 h. While in the heat-treated HAL, aluminum oxide phases of the α-Al2O3(amorphous) and γ-Al2O3(amorphous) types were found. Treatment at 400 °C for 1 h increased the HAL microhardness from 400 to 650 HV, and its abrasive wear resistance with fixed abrasive by up to 2.6 times. The ranking of various ways of hardening aluminum alloys relative to the D16 alloy showed that the abrasive wear resistance of heat-treated HAL is 20 times higher. Plasma electrolyte oxidation increased the abrasive wear resistance of the D16 alloy by 70–90 times, and its coating with high-speed oxygen fuel by 75–85 times. However, both methods are complex, energy-consuming, and require fine grinding of parts. Despite the lower wear resistance of HAL, their synthesis is cheaper and does not require the fine-tuning of parts. Moreover, despite the low hardness of HAL at present, hard anodizing is already commercially used to harden engine pistons, clamshell rotators, and pulleys.
