Key steps for establishing sustainable production
In a modern industrial environment, manufacturing facilities include various systems and processes, such as assembly, welding, machining and cutting, which are used to produce parts and finished products. With the world’s transition to sustainable practices, encouraged by global and European regulations, companies need to align their operations to achieve sustainable development goals.
Advantages of using engineering polymers for green (efficient) and sustainable hydraulic components
Engineering polymers have proven to have very promising tribological properties and successfully follow high-performance thermoplastics. In our research, we tested and analyzed polyoxymethylene (POM) for the very demanding operating conditions of hydraulic on/off valves.
Comprehensive Transformation of Production and Intralogistics Processes – Automation, Implementation of Digital Solutions, and Digital Twin
In the modern business environment, companies increasingly recognize the importance of automation and digitalization of production and logistics processes. This article presents the comprehensive transformation of production and intralogistics processes at the Herbarium company.
Prediction of the use of heat energy required for reheating the air in the mechanical ventilation system
In this article, we present the creation of a computer program for predicting the required heat for air reheating in a mechanical ventilation system. The process of creating a computer program is shown, which is based on the hourly change of the outside air temperature and the operating schedule of the ventilation device.
Characteristics of machining 6061 aluminum alloy with abrasive water jet in relation to standard SN 214001
In this study, we investigated the machining of 6061 aluminum alloy using abrasive water jet and compared it with the SN 214001 standard. Experiments were conducted at various water pressures and workpiece thicknesses, measuring surface roughness (Ra), kerf taper, inlet and outlet errors, and corner errors.
Use of 5G Technology in Manufacturing Processes and Systems
The advent of 5G technology opens up new opportunities for universal connectivity in manufacturing processes. This technology has the potential to play a crucial role in industrial environments by enabling faster, more reliable and more flexible connections between different subsystem of manufacturing systems. In the LASIM lab, we implemented 5G technology in the SMART FACTORY demo centre to demonstrate its potential.
Using Eigenresponse Fuzzy Clustering in a minimal-invasive supervisory system
Effective supervision of production processes is critical to ensuring product quality, maximizing production asset utilization, and improving overall performance metrics. However, the cost of implementing control systems can be prohibitively high, with such systems typically only being available on mass-produced machines.
Analysis of the welding transformer for the development of robotic resistance spot welding
In the automotive industry, resistance spot welding systems are used extensively for welding car bodies, where the welding transformer is installed on a moving robot, so the weight of the transformer is an important factor. The weight of the transformer can be reduced by a higher switching frequency, as a smaller cross-section of the iron core and thus the windings can be used, which significantly reduces the weight of the transformer.
Simulation of mechanical response for non-standard plugs
The paper depicts simulation activities performed with purpose of evaluation the mechanical response of a non-standard plug as a result of different loading scenarios. Detailed understanding of mechanical response of a plug can be understood as a prerequisite for the appropriate experimental validation, appropriate preparation of test samples and last but not least, also for the correct determination of guidelines for design of such components.
Air release of used hydraulic mineral-based oils
The presence of air in the hydraulic system or in the hydraulic fluid itself, either in its elementary form e.g., as an air pocket or bubble, or in the form of dissolved air, causes much inconvenience. This is manifested in the form of unwanted operation of the hydraulic system, causing accelerated ageing of the fluid, especially mineral oil.
