Design of CNC milling machines for modeling workshops
Kovács, Zdeněk ; Tůma, Zdeněk (referee) ; Pavlík, Jan (advisor)
This diploma thesis deals with the design of a CNC milling machine for the puspose of modeling workshop. In the first part is carried out the search in the field of small CNC milling machines for better familiarization with this issue. The information obtained in the first part of the thesis is used for determination the parameters of the designed machine. The last part deals with the design and realization in the form of a 3D model.

Deformation measurement of motorcycle components
Augste, Jan ; Novotný, Tomáš (referee) ; Tůma, Zdeněk (advisor)
The task of this diploma thesis is technical solution for deformation measuring of motorcycle components. By reason of the technical discretion, technology of measurement was changed to another, using image processing. Retrieval which describes fundamental principle of method named photogrammetry and the main conditions of measuring. For a practical testing the carbon composite tube of main motorbike fork was used. It was loaded a with a bending moment. Due to measuring technology was changed, so the design of loading bench was change too. In the end of diploma thesis is appreciation of practical experience discovered in writing of this thesis.

Design of a belt saw stand
Kropáč, Jan ; Pavlík, Jan (referee) ; Tůma, Zdeněk (advisor)
This bachelor thesis deals with research in the field of band saws, pedestals and roller conveyors. The output of this work is the design of a new stand for the older band saw PILOUS ARG 220 plus, which includes a foldable roller conveyor. The whole work is complemented by pictures and drawings from the model created in a 3D CAD software.

Connectivity control system to virtual reality system
Holešovský, Jiří ; Tůma, Zdeněk (referee) ; Bradáč, František (advisor)
This thesis deals with options of connecting the real control system to the immersive virtual reality system. Options of moving an object in IC.IDO are mentioned in the first part of the thesis. The theoretical part deals with commercial types of gaining data from control systém Sinumerik 840D sl and with programmable types of gaining data which means that there is no need to buy other licenses or software. Two g-codes were made in the experimental part. The first one provides feed of the machine in x axis and the second one reads position of the x axis of the machine and actual times. A script for IC.IDO which moves a model in IC.IDO exactly as the machine moved was written.

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.

Design optimization of the industrial part using finite element method and machine learning
Výbohová, Petra ; Tůma, Zdeněk (referee) ; Augste, Jan (advisor)
The object of research of my master thesis is optimization of 3D print using fused deposition modelling method. The goal of the thesis was to research influence of design parameters and mechanical properties and to come up with way how to research and optimize shapes for 3D print. Thesis is divided into 6 chapters. It contains 80 pictures, 12 tables and 4 attachments. The first part is theoretical research of optimization, finite element method and 3D print method. The second part is about 2 methods of 3D print, risk analysis and optimization.

Development of pressure switch for rail vehicles
Havelka, Ondřej ; Tůma, Jiří (referee) ; Tůma, Zdeněk (advisor)
This diploma thesis deals with the design of pneumatic pressure switch with adjustable hysteresis. In the thesis is carried out the introduction in the theory of compressed air and research of the pressure switches at the market. Based on the gathered information and customer specification, the design draft of the pressure switch has been created. In the thesis are described three main parts of the prototype: transform of the pressure, adjustable hysteresis and synchronization of the microswitches. In the end of the thesis is described the testing of prototype and summary of the results.
