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.

Volumetric accuracy of machine tools
Máčala, Daniel ; Marek, Tomáš (referee) ; Holub, Michal (advisor)
The diploma thesis deals with the influence of the volumetric accuracy of the machine tool on the size of the assessed work space. The impact assessment was carried out on the basis of tests of a three-axis vertical CNC machining center. The thesis is divided into two parts, theoretical and practical. The theoretical part is focused on geometric / volumetric accuracy of machine tools, measuring technique for measuring geometric errors and Design of Experiment. In the practical part, there is an analysis of the Design of Experiment according to Shainin, description of the work with the measuring instruments and the measurement of the geometric / volumetric accuracy of the machine including statistical evaluation. The output of the thesis is the description of the influence of volumetric deviation on the size of the measured work space by means of statistical methods.

Rationalization of machining technology
Plančar, Jakub ; Kalivoda, Milan (referee) ; Osička, Karel (advisor)
This diploma thesis is focused on a design of rationalization solutions for machining workplace in Siemens Company. The machined pieces are shafts, the basic components of the electric motors. The introductory part of this study describes the theoretical basics of machining technology, especially milling. The next part is focused on the company presentation, the analysis of the existing workplace and its technologies and components. In the following section are selected weaker production sites, and then is presented opportunities for improvement and rationalization of this workplace. Following the elaboration of the selected rationalization solution, along with techno – economic evaluation of the production change, which highlights the results of this study.

Clamping mode of tools and workpieces
Kamenická, Pavlína ; Pekárková, Eva (referee) ; Kalivoda, Milan (advisor)
This bachelor's thesis deals with a clamping of machine tools and workpieces in an engineering practice. It provides an overview of the possibilities of their clamping during machining. The individual ways of the clamping for specific machining operations are there presented sequentially and also their functional principles are described in detail. In the thesis is contained also a practical analysis acquired in a business environment. Its aim was to find out the real use of the clamping of machine tools and workpieces in practice. In the conclusion are added examples of typical clamping devices from catalogue sheets of various companies.
