Application of augmented reality in maintenance of production machines
Blaha, Jan ; Kroupa, Jiří (referee) ; Tůma, Zdeněk (advisor)
The master's thesis deals with the design of an augmented reality application for production machine maintenance. The thesis consists of two parts: the theoretical and the design part. The first part of the thesis summarizes the subject matter of augmented reality from a general point of view. It also includes an overview of leading manufacturers. The practical part of the thesis deals with application design. It contains the thought process from the database creation to the final prototype. Several possible solutions are listed, and the most suitable one is selected. The conclusion of the thesis contains a discussion of the results obtained, and practical recommendations for future uses.

Use of Virtual Reality Technology for Monitoring and Visualization of Selected Operational Charakteristics of Machines and Their Analysis
Augste, Jan ; Mostýn, Vladimír (referee) ; Szabó, István (referee) ; Knoflíček, Radek (advisor)
This dissertation deals with the study of the use of virtual technologies for an analysis of operating characteristics of a machine. Operating characteristics of a machine are parameters that determine the usability of the machine to accomplish a certain task in addition to the specified time and under the certain conditions. These include parameters that can be changed based on customer requirements, for example, the table size and the highest spindle speed to the parameters influenced from the start of the machine design such as positioning accuracy, acceleration value in the axes or consumption. The first part sets out general requirements for visualization of information and these are subsequently verified experimentally in the chapter devoted to the time visualization protocol. This thesis presents the original experiments to determine the basic requirements for visualization of a measured quantity, in this case the feed rate. By verifying usability when displaying these properties on the underlying data showing machine position change, the four basic requirements for visual data processing using immerse virtual reality are validated. A deeper insight into the work with data will enable to analyse more complicated relations within a longer period, greater transparency and clearer outputs of analysis.

Milling spindle thermal model
Chlapek, Ondřej ; Musil, Filip (referee) ; Hadraba, Petr (advisor)
The aim of this thesis is to create two thermal models (black box and grey box), which would allow to predict the development of the milling spindle temperature, based on measured operating data. The accuracy of both created models was determined by statistical methods, and the models were compared with each other.

Development stages in CNC machining
Dlouhý, Vít ; Strejček, Jan (referee) ; Kalivoda, Milan (advisor)
This bachelor thesis deals with machining with the use of CNC machines. In the introductory part is outlined a brief historical development of these machines. The following are characteristics associated with machining processes. In the next chapter it is described for machining on the classic conventional machine tools. Followed by the entry of computer technology into the field of machining and its impact. The last theoretical chapter summarizes the capabilities of the current machines CNC machine tools. In the final part is a description of the production of the selected rotational components produced by using CNC lathe.
