Abstract:
Introduction. Hole details are quite widely used in structures of construction and road machines. The specialists apply boring for draft, semi-fair, and in some cases for fair processing of such surfaces. This type of processing is often followed by the negative nature of oscillatory processes that leads to decrease in accuracy and in the surface quality. The paper studies the possibility of the calculation method’s usage in oscillatory processes, which allows assigning the cutting modes by providing required output parameters.Materials and methods. The authors used the double-support beam as a design model of a boring cutter. The solution of the fluctuations’ modeling came down to definition of point movements, which corresponded to cutter top (points of application equally effective cutting forces). The authors made the definition of movements with use of Mor integrals. Therefore, the paper considered the impact of chip formation and separation due to perturbing forces.Results. The authors carried out the calculation of forces’ values in cutting with use of the degree dependences. Moreover, the authors accepted the formation’s frequency as the frequency of the perturbing influenced structure. The frequency of the chip formation was defined on the basis of estimated dependences, which connected parameters of the tool, the cut-off layer and modes of cutting. As a result, the author received the implementations of oscillatory processes and studied the influence of different factors on vibration amplitude.Discussion and conclusions. The authors make assessment of the received results’ adequacy by comparison with experimental data. The error doesn’t exceed 20%. The developed model considers geometrical parameters of the tool (a departure, plate corners, etc.), the modes of cutting both mechanical properties of the processed material and parameters of the chip formation. The model can be used both at design of boring operations and by optimization of the cutting modes for the purpose of productivity increase.

Abstract:
The technology and organization of construction production using high-performance machines equipped with a diamond tool for machining concrete, concrete and stone surfaces is considered. Various installations, machines and mechanisms with a diamond tool for milling, grinding, drilling and cutting surfaces are presented. The design decisions of the grinding machine MSh-300, installations for machining the surfaces of facing slabs, a high-performance drilling machine and a concrete surface milling cutter are considered. An analysis of domestic and foreign installations has been carried out, which showed that the specific consumption of diamonds in domestic installations is lower with higher productivity. Having studied the sales statistics of manufacturers of individual machines and plants, as well as the positive feedback from implementing construction organizations, it is recommended to use, for the further prospect, high-performance machines and installations with a diamond tool in connection with an increase in the volume of reconstruction of industrial and civil facilities and the construction of transport highways.

Abstract:
Background and Purpose: The article is devoted to the reduction of energy consumption necessary for delimbing. Materials and Methods: Branch delimbing method includes feeding the tree trunk through the ring formed by the delimbing knives and simultaneous reciprocator movement of the delimbing knives along the axis of the processed trunk. The distinctive feature of the construction is the presence of the beater unit comprising a pusher and a piston mounted inside a sealed housing. Results: As a result of the suggested construction the force of the beater impact of the delimbing knife is increased. Using this method, the branches are removed not only due to the force generated when the knives come in contact with branches pushed by feed rolls moving the trunk, but also due to extra beater stress affecting the delimbing knife. The use of the aforesaid method and the construction of the mechanism allows to reduce energy consumption necessary for the delimbing process. Conclusions: The design of harvesting and processing head proposed in this article can be used in the design and manufacture of logging machines and mechanisms. The technical solution may be an interesting advance of the delimbing process when processing trees, especially when cutting big branches or when cutting forces are temporarily higher than average force values.

Abstract:
ObjectivesThe aim of the study is to revise design and calculation methods for metal cutting tools due to an increase in their quality requirements. The design of metal cutting tools necessitatesfinding a solutionto a number of issues related to their calculation, construction, manufacture and operation. However, the methods for solving these issues have always been dependent on the means that the toolmaker had at his disposal.MethodsContemporary electronic computers and digital equipment offersignificant opportunities for improving the process of machine tool design. To solve this problem, it is necessary to generate calculation methods that aresufficiently analytical to becapable of rigorously formalising the entire designing process. They have to support clearly defined optimisation criteria and be of sufficient generalityto enable all problems associated with tool designto be solved in a complex manner. That is, these calculation approaches have to support methodologies for solving the problems of the surface shaping by tools, calculating the cutting schemes, as well as the strength and manufacturability of the cutting part.ResultsA flowchart of a calculation algorithm for designing and calculating the combined countersink-tap toolhas been developed, allowing the process of calculating its basic parameters to be automated according to a predefined programme. ConclusionThe developed flowchart of the calculation algorithm with the preset programme allows the process of calculating the basic parameters of the combined countersink-tap tools, used for threading in the parts of ship machines, mechanisms and ship fittings from hard-to-process materials, to be automated. The flowchart can similarly be used to automate the process of calculating the parameters of any cutting tools used to process any materials.

Abstract:
The operating experience of metal-cutting machines made it possible to develop reasonable recommendations for the permissible limit values of temperature for the main subsystems of the machine, which determine the accuracy of processing. However, the decrease in the seriality of the manufactured metal-cutting equipment and the constant improvement of its designs require the development of models that are the basis of engineering techniques that allow at the design stage to predict the thermal picture of the main machine units that affect the processing accuracy. In connection with a significant number of factors influencing the formation of contact thermal resistance, and the difference in the weight of their action, it is proposed to use a pseudolayer (pseudo-medium), consisting of areas of actual contact and cavities filled with air or oil, for their comprehensive consideration in the thermal model of joining parts. To determine the significant factors that dominate the contact thermal resistance, a number of one-factor experiments were carried out. To develop a regression model of temperature change in the contact zone, a PFE of type 24 was performed. The results obtained were verified by the Cochran, Student and Fisher criteria.

Abstract:
As the machine tool industry moves towards high speed and high precision, we must have detection technology for the mechanical properties of fasteners, in order to overcome technical bottlenecks. This article is especially aimed at machine tools and special-purpose machines that commonly use clasp locking precision locknuts. In this research, the anti-loosening characteristics of precision nuts are investigated under different conditions, such as the clearances, end processing methods, nut cutting speeds, lubricants, and tightening speeds. The results can provide the precision nut manufacturers a data base for product design. The experimental results show that with the end surface machining method using concentric grinding, nut cutting speed 800rpm, 2rpm speed of tightening, and the use of lubricant 2TML, the nut has better anti-loosening characteristics.

Abstract:
In the process of continuous urbanization construction, the construction scale of urban landscaping projects is getting larger. At the same time, the design and the maintenance of the management is becoming more important. Recently, the rocketing development of the ternary world of many people, machines, and things has triggered the generation of multisource fusion data and the development of artificial intelligence technology, and the world has entered the era of multisource big data intelligence. Multisource data refer to the fusion of multiple types of data with effective characteristic information, which has richer, more comprehensive, more detailed, and more effective information than a single data source, and can provide high-quality data sources for various complex problems. Therefore, more effective data can be provided for the definition of urban fringe areas. From the moment Google’s AlphaGo defeated Go world champion Li Shishi, the chess game has been occupied by AI, setting off an upsurge in the study, research, and application of AI technology. Colleges and universities around the world have followed suit and set up AI-related majors. Deep learning is one of the cutting-edge technologies in the field of artificial intelligence. It is a method to solve complex real-life problems by extracting effective information from the data and mining key features on the basis of a large amount of learning and computing data.

Abstract:
According to the Ministry of Environment (KLH), Indonesia's average population produces 189 thousand tons of garbage per day. Of this amount, 15% is plastic waste or 28.4 thousand tons of plastic waste per day. The famous handling of plastic waste is 3R (Reduce, Reuse, Recycle). Reduce is reducing the purchase or use of goods made from plastic, especially disposable items. Reuse is the repeated use of plastic-based items. Recycle is recycling goods made of plastic. The method used in this design study is to use SolidWorks software by combining the literature study VDI221 to obtain a variant of the design results that will be used. The study results do a plastic bench machine that is integrated to produce plastic seeds, which are PET-shaped, which are extruded in a device that has been brewed. From the results of the design in the data processing and design specifications of the PET plastic waste-processing machine with the extruder method, the construction consists of several units, namely, Shredder unit, Extruder unit, Cutter unit, and Machine frame. The shredder unit serves to destroy plastic waste that is still intact in pieces before being processed in the extruder unit. The extruder unit functions to melt PET waste to be extruded using a screw. The cutter unit operates to cut processed extrusion waste into pellet granules. The engine frame is used to support the entire engine unit. The results of the Plastic Waste Extruder Machine design process with an Autodesk inventor are summarized in the following specifications: machine dimensions are 1625 mm long, 300mm wide, and 1325mm high; screw extruder uses a metering screw type with a diameter of 50.8mm (2 inches) with a length: diameter ratio of 20: 1, so the screw length is 1016mm, estimated throughput rate = 84 lb/h (42kg / h), the motor used is 5.5 PK (4 KW) with a rotation speed of 1450.

Abstract:
Based on the research carried out within the Research Institute for Construction Equipment and Technology—ICECON S.A. Bucharest, consisting of the design and development of vibrating-action machines and of the technical analysis of optimization of the technological processes with vibrating equipment for highway construction works in Romania. Moreover, the physical and mathematical modeling of this mechanical system used the data obtained in the activity of the certification of the technical level of capability of the processing equipment in industry and construction, taking into account the provisions of procedures and regulations legally enforced by normative documents. These are based on a parametric analysis of the dynamics of the technological processing vibratory equipment and machines. Thus, both the evaluation method and the parametric optimization procedure were established. In this context, this paper presents a numerical analytical approach with discrete and continuous parametric variations, from where favorable areas of operation can be established. In this way, the optimization criteria in stabilized harmonic vibration regimes are approached based on the assessment of the vibration amplitude, of the force transmitted to the processed material and of the energy dissipated in the system. The presented dynamic model as well as the specific parameters were used in the design and/or numerical and experimental assessment for vibrating rammers with the amplitude of the perturbing force from 2 kN up to 100 kN, vibrating compactors with the amplitude of the perturbing force from 100 kN up to 200 kN and vibrating sieves for mineral aggregates with surface sieves of 6, 12 and 18 sqm. The symmetry/asymmetry properties are specific to the dynamic response in steady-state technological regime. Thus, the amplitude of vibrations in resonance presents asymmetry through a functional level necessary for the technological regime. The maximum force transmitted in the technological process is asymmetric in relation to the variation of the excitation pulsation; also, the dissipated energy has asymmetries in the postresonance. Hysteresis loops are symmetrical to the main axis. The originality of the research results comes from the establishment of dynamic parameters for the amplitude of technological vibration, the force transmitted to the working part, the energy dissipated on the cycle, hysteresis loops in a steady-state regime with digital display to identify the dynamic regime and the damping in the system. The calculation relations are specific to machines with a vibrating action and, on their basis, the vibrating equipment from Romania were designed, manufactured and tested, as mentioned in this paper.

Abstract:
The design, construction, and longevity of nuclear facilities rely on high quality information being collected, managed, and made available to the designers and engineers who need it. They require quick and easy access to a wide variety of material information: micrographs, stress-strain curves, fatigue and creep curves, corrosion measurements and images, reports, and test data files. Moreover, inter-relationships (e.g., between design data, test data, processing history, and service history) must be carefully captured to ensure traceability. Information alone is not enough: tools are needed to manage, search, and apply this information—for example finding corrosion data from similar pipe joints across multiple applications, and using this experience to make the right choice in subsequent projects. Data needs to be stored in a consistent format to enable comparison of tests over long time-periods, and it must be possible to accurately export it in a wide variety of formats. Looking forward, automatic data capture from test machines and field engineers can ensure accuracy, traceability, and consistency, as well as improving feedback to design engineers from service history and in-the-field test data and experience. This paper shows how meeting these information management needs can help promote innovative, safe, and cost-efficient design.

Abstract:
“Sustainability” has become a ubiquitous term in almost every field, especially in engineering design and manufacturing. Recently, an increased awareness of environmental problems and resource depletion has led to an emphasis on environmentally friendly practices. This is especially true in the manufacturing industry where energy consumption and the amount of waste generated can be high. This requires proactive tools to be developed to carefully analyze the cause-effect of current manufacturing practices and to investigate alternative practices. One such approach to sustainable manufacturing is the combined use of Discrete Event Simulation (DES) and Life Cycle Assessment (LCA) to analyze the utilization and processing of manufacturing resources in a factory setting. On an economic aspect such method can significantly reduce the financial and environmental costs by evaluating the system performance before its construction or use. This project considers what-if scenarios in a simplified golf ball factory, using as close to real-world data as possible, to demonstrate DES and LCA’s ability to facilitate decision-making and optimize the manufacturing process. Plastic injection molding, an energy-intensive step in the golf ball manufacturing process, is the focus of the DES model. AutoMod, a 3-D modeling software, was used to build the DES model and AutoStat was used to run the trials and analyze the data. By varying the input parameters such as type and number of injection molding machines and material used, the simulation model can output data indicating the most productive and energy efficient methods. On a more detailed level, the simulations can provide valuable information on bottlenecks or imbalances in the system. Correcting these can allow the factory to be both “greener” and more cost-effective.
