In this article on the maintenance of hydraulic equipment, we will discuss the difference between monograde and multigrade hydraulic oils. Hydraulic oil differs from all other lubricants because it must primarily fulfil two main functions: energy transmission and lubrication. In addition, it must prevent foaming, release entrained air bubbles, be thermally, oxidatively …

Hydrostatic machines are devices that transfer power using pressurized hydraulic fluid within a closed circuit, relying on positive displacement pumps and motors. They convert mechanical energy into fluid pressure and back into mechanical torque. Simulation of such machines still requires highly skilled engineers…

In modern manufacturing, competitiveness is no longer determined solely by production quality, but by a company’s ability to manage a complex combination of orders, deadlines, materials, machines, people and other limited resources quickly and reliably. This is precisely where traditional ERP systems often reach their limits…

Modern industrial manufacturing, characterized by high degree of variability and dynamically changing production demands, encourages the development on flexible, adaptable, and reconfigurable automated machinery. Those industrial trends are reflected directly onto the curriculum of contemporary education programs in the fields of automation and robotics…

Varnish deposits represent one of the key, yet often overlooked, causes of reduced reliability in modern hydraulic and lubrication systems. Their impact does not manifest as sudden failures, but rather as a gradual degradation of performance, which can lead to valve sticking, reduced efficiency of control components, and unplanned equipment downtime…

Hydrostatic machines are devices that transfer power using pressurized hydraulic fluid within a closed circuit, relying on positive displacement pumps and motors. They convert mechanical energy into fluid pressure and back into mechanical torque…

Artificial intelligence and machine learning are increasingly shaping the development of modern smart manufacturing systems, where reliable and efficient operation is strongly dependent on accurate awareness of machine states and process conditions. In this paper, the practical applicability of data-driven methods is demonstrated through a representative case study of a hydraulic press used in sheet metal bending operations…

The paper addresses the development of energy digital twins for discrete manufacturing processes with the aim of improving energy consumption management. Due to increasing price volatility of energy sources and the demands of the green transition, accurate energy consumption forecasting is becoming crucial for maintaining companies’ competitiveness…

The paper presents modern approaches to end-of-line (EoL) quality inspection, i.e. the final inspection stage in the manufacturing process of electric motors, based on artificial intelligence. Traditional EoL systems rely on extensive signal processing and expert-defined features and thresholds…

In modern industrial production, there is a tendency to optimize manufacturing processes, with a special emphasis on reducing energy consumption and waste and maximizing manufacturing flexibility. In forming processes, customers’ need to narrow manufacturing tolerances increases production complexity…
