Opis:
The most recent tendencies and breakthroughs in digital technologies have made it possible to implement a new model of manufacturing. By es-tablishing a digital twin of the real environment and basing their judg-ments on that twin, digital systems are able to monitor, optimize, and man-age the processes that they are applied to. This concept is predicated on the creation of a “Digital Twin” for each individual production source that contributes to the overall manufacturing process. In spite of the fact that different real-world applications of digital twin may involve different tech-nical and operational specifics, a significant amount of work was put in over the past few years to recognize and express principal properties, in addition to the primary challenges involved in the practical implementa-tion of digital twins within related industries. The purpose of this article is to review and analyze the fundamental principles, ideas, and technological solutions that comprise the Digital Twin vision for production processes. As a result, the objective of this review is to provide a synopsis of the state-of-the-art regarding digital twin concepts and to analyze their most recent status in terms of their potential application and implementation.

Opis:
This review paper focuses on the up-to-date machinability characteristics of milling processes such as cutting forces, surface roughness and tool wear and their impacts on the cutting mechanism. The methodology pur-sued in this paper is to analyze the previous research articles published between 2019–2022 classifying them into the subcategoriesthat usemill-ing operation as manufacturing strategy. As known, milling is one of the most used machining processes in industry and often applied for academic studiesforawide range of materials. Therefore, used sensor systems, main aim and the preferred methodology were summarized in the context of this paper. Seemingly, a great number of machinability papers have been published recently which focuses on the several types of engineering ma-terials and utilized various types of sensor system to improve the surface roughness and tool life. In addition, the investigation showed that optimi-zation approaches have been applied broadly to detect the best machining conditions. Also, it was observed that several modeling approaches such as finite element analysis is a good alternative to analyze the process.

Opis:
Artificial intelligence is a field that has been rapidly developing in various areas of knowledge in recent years. Its application in medicine can support the intensive development of research in health care and improve and ac-celerate the operation of many medical facilities. This article presents sev-eral examples of expert systems that can find application in diagnosing and preparing a patient for selected tests. Expert systems can also find appli-cation in the rapid selection of rehabilitation, medical or support equip-ment and devices with which medical facilities are supplied. In this article, the reader will also find a sample application that will perform this func-tion. The article presents the elements of which a correct expert system should consist. For each application, tests have been carried out to show the correctness of the system. The purpose of the article was to show the capabilities of the expert system and its application in medical fields.

Opis:
An anthropomorphic robot, i.e. a robot that can reproduce the movements of the human arm, is equipped with various types of interpolation. The ro-bot can be used to mix two liquids enclosed in a shaker mixer. The problem that has to be solved is the selection of the optimal types of interpolation, as well as the sequence of these robot movements that is able to provide better results higher mixing efficiency, in other words amore sustainable approach to the mixing process, using an anthropomorphic robot.The shaker-type container used the shape of a truncated cone has a positive effect on the efficiency of the liquid mixing process. The difference in den-sity between the two liquids contributes to a sustainable approach to the mixing process. It is preferable to use different shaker position with re-spect to the gravitational acceleration vector and to use different linear and arc interpolation. The use of variable position in relations to gravita-tional acceleration vector, due to the shape of the truncated cone of the mixer, will cause chaotic movement of particles inside the shaker, which is a desirable phenomenon, because then both mixed liquids mix quickly

Opis:
Electrical discharge machining (EDM) is a non-traditional machining process widely used in manufacturing to create complex geometries on hard-to-machine materials. The tool material used in EDM plays a crucial role in determining the machining performance and final surface finish of the workpiece. In this research, we aimed to optimize the tool selection for creating circular holes on SG iron (grade 450/12) using EDM. To this end, we employed a step-wise weight assessment ratio analysis (SWARA) based combined compromise solution (CoCoSo) approach to evaluate the performance of different tool materials under various machining conditions. The machining conditions considered in this study included peak current (I), pulse-on time (Ton), and inter-electrode gap (IEG). The results of our study showed that the CoCoSo approach is an effective method for tool selection in EDM, and it can be used to identify the optimal tool material and machining conditions for creating circular holes on SG iron. The final appraisal scores obtained from the ranking of tool materials indicated that copper tools scored highest (2.4767, ranking 1), followed by copper tungsten (2.3615, ranking 2), while brass scored lowest (1.6606, ranking 3). Furthermore, Spearman's rank correlations for different integrated MCDM techniques were performed, which demonstrated the efficacy of this technique. It has been demonstrated that implementing the SWARA-CoCoSo method can effectively optimize the EDM process with regard to sustainable machining practices.
