[popis] => Wire Electrical Discharge Machining (WEDM) is an unconventional machining technology, widely spread in different sectors of many industries. The machining uses periodically repeating electrical impulses, which allows all materials with at least a minimum electrical conductivity to be machined. The machining tool is a thin wire that can be made of many different materials. Wire electrode material requirements vary from industry to industry. This study aimed to increase the efficiency of WEDM through an analysis of the influence of the type of wire material on the machining of Albromet W130 copper alloy. The analysis comprised a molybdenum, brass and a copper wire of a 0.25 mm diameter and a Box-Behnken design of experiment totalling 42 rounds. The design of experiment results analysis covered cutting speed, machined surfaces' topography and morphology, and the subsurface layer condition. Furthermore, an analysis of the wire electrodes used in the experiment was carried out. The highest cutting speed was achieved using a copper wire and the lowest R a values were achieved in samples machined with a molybdenum wire.

[popis] => Wire Electrical Discharge Machining (WEDM) technology represents an unconventional but vital manufacturing technology in many different industrial branches. The automotive industry and its many significant requirements bring the need to manufacture inserts and mould segments for plastic injections from Albromet W130 material, with a required roughness, Ra, from 4.5 to 5 mu m so that subsequent profile etching can be eliminated. A planned experiment of 60 rounds was carried out to discover the optimal machining parameters, namely, the pulse-off time, gap voltage, discharge current, pulse-on time, and wire speed in order for the thickness of 10 to 100 mm (after 10 mm) to demonstrate the required roughness. The goal was to evaluate the surface roughness, maximise the cutting speed, and manufacture it without surface or subsurface defects. The evaluation of the planned experiment led to the establishment of optimised WEDM machining parameters with which thicknesses of 10-100 mm will always be produced with the required roughness, Ra, from 4.5 to 5 mu m and with the highest possible cutting speed. It was also proven that the machining does not lead to surface or subsurface defects, and thus, the service life of the manufactured parts will not be affected.

[popis] => Wire Electric Discharge Machining (WEDM) is an unconventional machining technology that uses electrical impulses to generate very high temperatures to cut material. The WEDM process hence causes some unfortunate defects, such as cracks and burnt cavities, which can impact the correct functionality of the machined pieces and shorten their service life. This study was carried out to understand which materials remain defect-free after WEDM. The examined materials were the Ampcoloy 35 copper alloy, the high-entropy steels FeCoCrMnNi and FeCoCrMnNiC0.2, and the B1914 and Nimonic 263 nickel alloys. The influence of the machining parameters, namely the pulse off time, gap voltage, discharge current, pulse on time, and wire feed, on the cutting speed and the surface topography of the machined piece was investigated. The surface morphology, the state of the subsurface layer in a cross-section, and the number of diffused elements from the wire electrode were analysed. All the analysed materials were found completely suitable for WEDM machining as they do not form any surface or subsurface defects.

[popis] => Technical diagnostics is a separate scientific discipline focused on non-destructive methods of assessing the technical condition of objects and is one of the pillars of reliability and functionality of equipment. The definitions of technical diagnostics are based on various disciplines and standards, and technical diagnostics relies on the monitoring of diagnostic variables such as temperature, vibration, noise, and others. The paper further discusses the types of diagnostics, including vibrodiagnostics, thermodiagnostics, electrodiagnostics, etc., and their division into on-line and offline systems. The next section is focused on data evaluation, which is based on standards and methods, including frequency analysis and the use of artificial intelligence. The paper also discusses the use of cloud computing, edge computing, and risk theory, which can contribute significantly to the efficiency of diagnostic processes in the future. Finally, practical examples that have been solved at our department are presented. The first one is the use of the SIPLUS CMS1200 system for on-line vibration monitoring, which demonstrates its functionality and possibilities of use in industrial practice. The second example is the possibility of using neural networks in the processing and evaluation of measured data. The last example focuses on the application of risk theory in the evaluation of different diagnostic methods. The article aims to introduce the reader to the issues of technical diagnostics and then demonstrate possible approaches for practical solutions.

The paper further discusses the types of diagnostics, including vibrodiagnostics, thermodiagnostics, electrodiagnostics, etc., and their division into on-line and offline systems. The next section is focused on data evaluation, which is based on standards and methods, including frequency analysis and the use of artificial intelligence. The paper also discusses the use of cloud computing, edge computing, and risk theory, which can contribute significantly to the efficiency of diagnostic processes in the future. Finally, practical examples that have been solved at our department are presented. The first one is the use of the SIPLUS CMS1200 system for on-line vibration monitoring, which demonstrates its functionality and possibilities of use in industrial practice. The second example is the possibility of using neural networks in the processing and evaluation of measured data. The last example focuses on the application of risk theory in the evaluation of different diagnostic methods. The article aims to introduce the reader to the issues of technical diagnostics and then demonstrate possible approaches for practical solutions.

[popis] => This paper presents the development and verification of a novel dual plunger hybrid kinetic energy
harvester, which combines piezoelectric and electromagnetic conversion principles to effectively generate
electricity from ambient mechanical motion and vibrations. This device utilizes two cantilevered steel plungers
forming a parallel mechanism which makes non-arc oscillations, therefore maximizing energy harvesting
efficiency. A single degree of freedom model is initially proposed for description, which is later extended
to incorporate nonlinear effects with magnets. The paper discusses the optimization of resistance parameters,
preliminary experimental measurements on the adhesive type and thickness for piezoelectric patches, as well
as the measurement of the damping factor. Additionally, the verification and validation of the model through
frequency sweeps for different input acceleration levels are detailed, along with the refinement of the model
based on manufactured samples.

[nazev_orig] => Power Optimization of Hybrid Energy Harvestering from Mechanical Vibrations Using Piezoelectric and Electromagnetic Mechanisms
[duvernost_udaju_id] => S
[popis] => The rise of wireless sensing technologies and the Internet of Things has created a growing demand for efficient hybrid energy harvesting systems. This paper presents a necessary analysis of such a hybrid system, combining both piezoelectric and electromagnetic mechanisms to generate electricity from mechanical vibrations. This analysis is a crucial step for efficient implementation into industrial applications, ensuring that the system can meet practical performance requirements. The focus is on optimizing resistive loads for both circuits to maximize power output and improve energy conversion efficiency.

[popis] => Numerous studies have focused on the embedding of objects through 3D printing, particularly in applications involving sensors and smart materials, which hold great promise for the Internet of Things (IoT). Embedding technology in additive manufacturing presents significant advantages for future innovations. However, conventionally it often requires interrupting the printing process to manually insert objects, leading to various inconveniences and uncertainty. This study focuses on automating the embedding of components during the additive manufacturing process. A novel embedding method for bottom-up vat photopolymerization printing has been proposed in this paper. In this approach, the embedded object is fixed at the bottom of the resin tank, directly beneath the model's cavity, prior to sealing. This setup allows for continuous printing, facilitating automation without the need for modifications to the printer's hardware and leveraging the benefits of the bottom-up printing system. A prototype system was designed that incorporates the bottom-up printer alongside a device utilizing SMT technology for component placement. This setup enables the automated embedding of objects during the printing process. The demonstration of the prototype system confirmed the feasibility of the proposed method, successfully achieving the automated object embedding.
