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.

Smart bearings
Junek, Jaroslav ; Polnický, Vojtěch (referee) ; Hartl, Martin (advisor)
This thesis deals with the issue of smart bearing, which can be used to refine and determine the condition of the bearing. Due to its advantageous availability of the cyber-physical system as a suitable apparatus for industrial use. The links and connections within this system are mentioned here. The following is a summary of commercially available smart bearings. It is complemented by patent solutions and scientific studies, which could point to future developments in this area.

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.

Proactive machine maintenance system
Semotam, Petr ; Řezníčková, Hana (referee) ; Hammer, Miloš (advisor)
This bachelor thesis concerns issues of proactive maintenance, which is focused on machine tools. The most common failures and the most widespread methods of diagnostics of machine tools are described in the thesis. There are also described the procedure of Failure mode, effects and criticality analysis FMEA/FMECA, its possible development in the future with demonstrative presentation of application this analysis on CNC automatic lathe. Subsequently, in the practical part there has been chosen, described and appraised diagnostic of vibrations. Prior to the end the process in field of solving of establishment systems of maintenance has been recommended for SMC Industrial Automation CZ LLC Vyškov.
