    This paper presents the results of an investigation conducted on samples of high-quality heat-treated carbon steel using the magnetic noise method. The objective of the work was to find the proper informative parameters for identifying the obtained s tructures with different hardness. To this end, samples were prepared using quenching and tempering heat treatment at different temperatures , from 150°C to 500°C. After microstructural analysis and hardness measurements, the samples were investigated using the magnetic noise method. The signals were visualized and analyzed using a digital oscilloscope and the Multi Instrument 3.8 software program. The RMS informative parameters and the registration time of the magnetic noise signals were used to identify the obtained microstructures with different characteristics and hardness.

    This paper presents the developed domain ontology of the equipment in manufacturing systems in order to be used in the field of reconfigurable manufacturing systems (RMS). The ontology meets the requirements of the meta-class "Equipment", which is part of the developed meta ontology based on the standard for integrated systems for the production and management IEC / ISO 62264. The article explains various properties and class restrictions of the developed ontology. Web Ontology Language (OWL 2) and Protégé 4.3 as an editor and knowledge acquisition tool are used. Special attention is given to the use of ontology reasoning to infer additional information from the facts stated explicitly in ontology – an important feature, used to perform classification, sorting and assembly operations and consistency checking.

    This paper presents an approach for software development that generates control programs in the field of reconfigurable manufacturing systems. The proposed approach proposes the use of developed domain ontologies merged in a meta ontology which is based on the standard for integrated production systems and management IEC / ISO 62264. The article addresses the main graphic elements of the software that are being developed as well the principle of generating control programs.
