Machine tool Life Cycle
Mikulka, Tomáš ; Marek, Jiří (referee) ; Knoflíček, Radek (advisor)
The diploma thesis is focused on the determination of the life cycle state of the production machine. The thesis is divided into several chapters. First, the life cycle of the machine is defined, and the phrase used here is given. Subsequently, the work is devoted to maintenance, repairs and modernization of the production machine. Then there is a demonstration of Schaeffler Skalica's corporate structure and individual methods that determine the state of the machine's life cycle. In the next chapter, the machine is described and then the analysis is made for the current state of the machine. Then the analyses created are evaluated.

Design of machining process diagnostic system
Wolf, Jonatan ; Klapka, Milan (referee) ; Houfek, Lubomír (advisor)
The master’s thesis is focused on online diagnostics of the machining process. In the theoretical part are presented maintenance possibilities of machine tools. A whole chapter is devoted to vibrodiagnostics, which describes vibration sensors, their attachment to the measured object and methods of vibration signal processing. The practical part lies in creating a software diagnostic solution for chosen PLC and sensors. The functionality of the proposed system was verified during experimental machining, which also provided valuable data for the correct setting of the system.

Data collection from 3D printer
Fiala, Jan ; Baštán, Ondřej (referee) ; Arm, Jakub (advisor)
This work is dedicated to design and implementation of a funcitonal model for data processing from 3D printer using sensors in IoT concept. Measured data will be processed and transfered to basic units with connection to the cloud server for any ongoing work. Part of this work is selection of suitable sensors and system members, creation of a functional model of data transfer and its implementation on a 3D printer.

Using tribodiagnostics in predictive maintenance in company practice
Trost, Daniel ; Nahodil, Petr (referee) ; Hammer, Miloš (advisor)
The thesis deals with the use of tribodiagnostics in predictive maintenance in corporate practice. It is generally dealt with maintenance, then tribodiagnostics in the company Škoda Auto a.s. Used offline and online diagnostic tools are described. Emphasis is placed on verifying the functionality of the newly purchased online filter unit. The experimental part is focused on detailed analysis of the above, including comparison of measurement results offline and online diagnostics. There is also an economic evaluation of savings obtained by operation the online filter unit. In conclusion, the tribodiagnostics recommendations are given for Škoda Auto a.s.

Predictive maintenance of pneumatic pistons
Voronin, Artyom ; Rajchl, Matej (referee) ; Brablc, Martin (advisor)
Tato práce se zabývá vytvořením simulačního modelu dvojčinného pneumatického pístu s mechanickou sestavou, včetně modelů snímačů, s následujícím odhadem parametrů a aproximací chování demonstračního zařízení. Dalším cílem je prezentace různých přístupů prediktivní údržby na datové sadě měřené na demonstračním zařízení. Na měřený datový soubor se aplikovaly signal-based techniky bez použití simulačního modelu a model-based metody, které vyžadují použití simulačního modelu. Výsledkem této práce je ověření možnosti monitorování stavu zařízení pomocí nainstalovaných senzorů a vyhodnocení efektivity senzorů z hlediska přesnosti a finančních nákladů.

Virtual twin and predictive maintenance
Kotrba, Martin ; Holub, Michal (referee) ; Tůma, Jiří (advisor)
This diploma thesis deals with the design of a virtual twin of cross table MCV 754 QUICK from the Czech manufacturer Kovosvit MAS. The research part describes the basic principles of predictive maintenance methodology and virtual twin technology. The practical part includes a simplification of the initial cross table model. This model was then transferred to the simulation software MSC Adams, where it was optimized so that its behavior corresponds as closely as possible to the physical device. Several simulations were subsequently performed on the model. Then a concept for a predictive method for calculating the remaining service life of individual sections of the ball screw was presented. Simulations performed on a virtual twin served as a source of data to test the proposed method.

Proposal to Improve Maintenance Strategy in the Industry 4.0 Context
Milčíková, Nikoleta ; Maradová, Karla (referee) ; Zuth, Daniel (advisor)
This bachelor's thesis deals with a proposal of a maintenance strategy refinement in the context of Industry 4.0 in a selected company, particularly in the operating center of Subtil corporation located in Myjava. The first part of the thesis deals with the theory of maintenance itself, its strategies and development across industrial revolutions and the related theory of the Industry 4.0 concept and its cyber-physical principles. The practical part is devoted to the description of the current maintenance strategy in the company and the description of the current state of knowledge in the field of maintenance in the context of Industry 4.0. Subsequently, the findings are applied to the maintenance strategy of Subtil according to its needs and capabilities.
