Opis:: The article presents the research results on the influence of the PVD coating on the cutting tool on the surface roughness and energy consumption in the cast iron turning process. It was shown that using coated tools leads to obtaining a surface qualitatively corresponding to the ground surface and to reducing the power consumption of the machine tool. In addition, the process itself, carried out without a cooling and lubricating liquid, is more eco-friendly, as it excludes its use, disposal and negative environmental impact.

Opis:: This paper presents a new power measurement system which allows recording the power consumption profile and determining its components related to all the controlled axes. The system is based on computer processing of signals generated by current and voltage sensors connected to spindle and axis driving electric motors. It should be noted that these motors are controlled independently with different frequencies and voltages. By using LabVIEW data acquisition system, it is possible to record total power consumption and its components during a typical machining operation. This study concerns the power consumption in a sequence machining process consisting of hard turning and ball burnishing operations under variable machining conditions.

Opis:: This paper presents a concept of a wireless measuring system based on ZigBee modules, and the stages in its implementation. The distinctive feature of the built measuring systems is their high resistance to environmental conditions. To a large extent this was achieved through the use of induction charging. The effectiveness of this solution was determined by comparing it with conventional charging. The measuring modules built in accordance with this concept were tested in the work space of a machine tool during milling. Special attention was paid to the amount of power consumed by the tested modules during different modes of their operation. The response time of the modules during their operation in the work space of the working machine tool and in the case when the modules were completely immersed in water was tested. By comparing the measured response times the effect of the above factors on the correctness of operation of the measuring system was determined.

Opis:: Przedstawiono wyniki badań wpływu rodzaju słupów energetycznych średniego napięcia na wydajność agregatów maszynowych oraz zużycie paliwa podczas uprawy pszenicy ozimej. Na podstawie przeprowadzonych badań eksploatacyjnych stwierdzono, że największe straty z tytułu zmniejszenia wydajności i zwiększenia zużycia paliwa występują podczas zbioru ziarna wokół słupów odporowo-narożnych.
The research findings on the influence of medium voltage power transmission poles on the efficiency of machine units and fuel consumption during winter wheat cultivation were presented. On the basis of the conducted operational research it was determined, that the greatest loss on account of efficiency decrease and fuel consumption increase occurs during wheat collection around the section corner posts.

Tytuł:: Predictive maintenance of induction motors using ultra-low power wireless sensors and compressed recurrent neural networks

Opis:: In real-world applications - to minimize the impact of failures - machinery is often monitored by various sensors. Their role comes down to acquiring data and sending it to a more powerful entity, such as an embedded computer or cloud server. There have been attempts to reduce the computational effort related to data processing in order to use edge computing for predictive maintenance. The aim of this paper is to push the boundaries even further by proposing a novel architecture, in which processing is moved to the sensors themselves thanks to decrease of computational complexity given by the usage of compressed recurrent neural networks. A sensor processes data locally, and then wirelessly sends only a single packet with the probability that the machine is working incorrectly. We show that local processing of the data on ultra-low power wireless sensors gives comparable outcomes in terms of accuracy but much better results in terms of energy consumption that transferring of the raw data. The proposed ultra-low power hardware and firmware architecture makes it possible to use sensors powered by harvested energy while maintaining high confidentiality levels of the failure prediction previously offered by more powerful mains-powered computational platforms.
