Capability assessment of a optical measuring instrument
Slíž, Michal ; Šrámek, Jan (referee) ; Jankových, Róbert (advisor)
The diploma thesis deals with the capability assessment of an optical coordinate measuring machine according to VDA 5. The capability assessment is an effective tool for deciding whether the evaluated measuring machine is capable for the intended use and under which conditions its use is possible. The theoretical part of the thesis is devoted to the analysis of coordinate measuring machines, with a closer focus on a subset of optical measuring machines and the analysis of their capability assessment procedures. In the practical part of the thesis, the selected procedure is applied on the specific measuring machine Micro-Vu Sol 311. The main contribution of this thesis is a description of the possibilities of the considered coordinate measuring machine for its further use in the educational process at the Faculty of Mechanical Engineering of Brno University of Technology.

Assessment of weld defects during laser welding with beam wobbling of aluminum alloy
Slíž, Michal ; Šebestová, Hana (referee) ; Mrňa, Libor (advisor)
This bachelor thesis is aimed on assessment of weld defects during laser welding with beam wobbling of aluminum alloy. Theoretical part deals with study of main types of industrial lasers, laser modes and analysis of beam wobbling technique. Further described aluminum alloys, their weldability, weld defects and methods of their evaluation. In the experimental part, sixteen test welds are made on sheet metal from aluminum alloy AlMg3. This is followed by the evaluation of the defects and determination of optimal welding parameters.
