The paper presents the environmental, economic and exploitation aspects of the use of burnishing rolling treatments. The validity of the application of the plastic surface treatment in modern technological processes by replacing expensive, energy-intensive defects processing (grinding, turning) was shown. One confirmed the possibility of obtaining resource saving products using burnishing with not worsen their utility quality as well as a lower unit price compared to products prepared using conventional technology.

Currently, the manufacturing management board applies technologies in line with the concept of Industry 4.0. Cyber-physical production systems (CPSs) mean integrating computational processes with the corresponding physical ones, i.e., allowing work at the operational level and at the strategic level to run side by side. This paper proposes a framework to collect data and information from a production process, namely, the burnishing one, in order to monitor real-time deviations from the correct course of the process and thus reduce the number of defective products within the manufacturing process. The proposed new solutions consist of (i) the data and information of the production process, acquired from sensors, (ii) a predictive model, based on the Hellwig method for errors in the production process, relying on indications of a machine status, and (iii) an information layer system, integrating the process data acquired in real time with the model for predicting errors within the production process in an enterprise resource planning (ERP) system, that is, the business intelligence module. The possibilities of using the results of research in managerial practice are demonstrated through the application of an actual burnishing process. This new framework can be treated as a solution which will help managers to monitor the production flow and respond, in real time, to interruptions.

In the manufacturing of machine elements was important to technological quality products. In surface engineering one of the economic and ecological treatments used for technological properties were burnishing rolling – pressuring process. This is a surface plastic forming a local plastic deformation based on the overall impression given by smooth and hard tool. In production, engineering cylindrical outer surfaces (e.g. plugs propulsion shaft centrifugal pumps seawater) were finishing. You can therefore propose burnishing in exchange for abrasive machining. The article presents the influence of parameters for burnishing rolling – pressuring process on the degree of relative strain hardening and surface roughness reduction ratio. Burnishing process carried out for 316L stainless steels. After the experimental study, it was determined that there was an increase in hardness and a decrease in roughness of the top outer cylindrical layer of stainless steel, which can be applied to the centrifugal pump shafts ship. Important question to determine in the article of the research was to receive appropriate technological quality. The burnishing due the technological and economic aspect in the production of machine parts in exchange for the abrasive processing can be used. After the experiments, it was found that the technical parameters are influenced by the hardness and the roughness of the outer cylindrical surfaces and the material ratio curve a convex shaped, which, taking into account the load capacity of the surface will be directly affected by its resistance to wear and corrosion of the surface layer.

Purpose: The aim of the study was description to the influence of technological parameters of burnishing process on the degree of relative strain hardening and surface roughness reduction ratio. Design/methodology/approach: Burnishing process carried out for stainless steels X2CrNiMo17-12-2. After the experimental research, it was determined that there was an increase in hardness and a decrease in roughness. The hardness was measured with the use of Vickers hardness tester. Observation of the microstructure of stainless steel samples was carried out using scanning electron microscopy and optical microscopy. The parameters of surface roughness measurements were performed to the principles contained in ISO standards. Findings: In the production and regeneration of metal products used in machine elements is important to technological quality surface layer. In surface engineering one of the ecological and economic treatments used for endurance and technological properties is burnishing. This is a surface forming a local plastic deformation based on the overall impression given by smooth and hard tool. Practical implications: The burnishing due the technological and economic aspect in the production and regeneration of machine parts in exchange for the abrasive processing can be used. In production engineering or technology of repair cylindrical outer surfaces (e.g. plugs propulsion shaft centrifugal pumps seawater) are finishing. You can therefore propose burnishing in exchange for abrasive machining. Originality/value: Important question to determine in the article of the research was to received appropriate technological quality. After the tests, it was found that the technological parameters are influenced by the hardness and the roughness of the outer cylindrical surfaces and the material ratio curve a convex shaped, which, taking into account the load capacity of the surface will be directly affected by its resistance to wear and corrosion of the surface layer.
