Data processing from measurement on machine tools
Pokorný, Zdeněk ; Vetiška, Jan (referee) ; Holub, Michal (advisor)
The Master’s thesis deals with the precision of machine tools, especially with the three-axis vertical milling machine. It is structurally divided into a theoretical and practical part. While the theoretical part focuses on problems of geometric errors and measuring devices, the practical one is devoted to the machine tool being tested. In this case, the data processing and the proposed statistical analysis are essential, and at the end of the thesis another possible way of developing the data processing is outlined.

Application of modern technologies for design and production of a ski helmet prototype
Vilímovský, Daniel ; Pokorný, Zdeněk (referee) ; Sedlák, Josef (advisor)
The diploma thesis is focused on the application of modern technologies in ski helmets development. In the theoretical part is performed the research of the protective gear for skiers including the characteristics of production technologies used for its production. Part of the thesis is also the characteristics of Reverse Engineering and Rapid Prototyping. The practical part deals with the design of the ski helmet using modeling clay with the following conversion to a computer model and editing in available CAx program. Part of the practical part is also production on 3D printer. The thesis is concluded with a technical-economic evaluation of applicated modern technologies used for prototype helmet model production.

Quality – Condition of Competitiveness
Pokorný, Zdeněk ; Řezníčková, Hana (referee) ; Fiala, Alois (advisor)
This thesis deals with issues related to quality – a condition of competitiveness. The introductory chapters define key words and they are followed by a product characteristic. The next chapters are devoted to the analysis of the particular methods, techniques and tools for improving quality, especially the strategies - Six Sigma and KAIZEN. In conclusion the possible future development in the area is outlined.

Chemical-heat treatment of steels
Rozum, Jakub ; Pokorný, Zdeněk (referee) ; Sedlák, Josef (advisor)
This thesis deals with study of surface layers of low-carbon steels formed by chemical-heat treatment. The first three chapters consist of theoretical part of the thesis, there are explained basic physical principles of these technologies and described individual types, the third chapter deals with the application of chemical-heat treated low-carbon steels in mechanical engineering. The experimental part of thesis deals with analysis of surface layers of two low-carbon steels formed using plasma nitrocarburizing and gas nitrocarburizing. The properties of these layers are evaluated based on the results of mechanical tests (hardness tests) and observation of microstructure. The thesis is completed by discussion, where the achieved results are evaluated.

Design of Creating a Production Concept for Production Process Control Functions
Pokorný, Zdeněk ; Jablonka, Ján (referee) ; Jurová, Marie (advisor)
The Master’s thesis deals with the approaches to the introduction of the principles of lean manufacturing and especially the concept of Just in Time (JIT). It is structurally divided into theoretical and practical part. While the theoretical part focuses on the theory of lean manufacturing and the details about steam turbines, the practical part gradually deals with the introduction of the company, production portfolio, supplier analysis and especially the production process. The practical part ends with the selection of proposals for changes in the production concept, including partial economic evaluations with regard to customer requirements to meet delivery dates, quality and required costs.

Cutting Tests of Insert for Turning Structural Hardened Steel
Šolc, Michal ; Pokorný, Zdeněk (referee) ; Sedlák, Josef (advisor)
The thesis deals with the wear of replaceable inserts during the turning of structural hardened steel. The theoretical part describes a brief characteristic of turning technology, force loading on tools and tools used in turning. Moreover, it contains an analysis of the chemical composition of the machined material, its microstructure and microhardness. Machines and equipment used for the experiment and their specifications. The experimental part of the thesis describes the method of measuring and evaluating of tool wear, followed by the cutting tests themselves, documenting of the result and their evaluation. The conclusion of the thesis is the processing of measured data, the evaluation of achieved results and the proposal of further steps to improve the process.
