Evaluation of Surface Texture Profile Parameters and Verifying of Conformity with the Specification in the Drawing
Houdková, Eva ; Jankových, Róbert (referee) ; Sámelová, Vendula (advisor)
The first part of this thesis investigates current state of the art in the field of surface texture and methods of its evaluation. It also deals with the issue of evaluating surface texture using profile method, including consideration of measurement uncertainties. Subsequently, it is focused on proposing solution of given issue. In the second part of the thesis samples are being measured by contact profilometer and profile parameters values are calculated in the program TalyProfile Lite. The proposed solution was then applied to the measured values of the mean arithmetic height of the roughness profile. This parameter was evaluated according to the proposed combination of standards ČSN EN ISO 4288 and ČSN EN ISO 14 253-1. Evaluated results were then compared with the case where the surface was evaluated only according to the ČSN EN ISO 4288 standard. Thanks to the comparison, it was possible to conclude that the evaluation method according to ČSN EN ISO 4288 is more tolerant than evaluation considering both standards and thus measurement uncertainties.

Optical measuring instrument SOL 311
Kellerová, Michaela ; Šrámek, Jan (referee) ; Jankových, Róbert (advisor)
The main benefit of this bachelor thesis is the assessment of conformity with the specification in accordance with the ISO GPS system. In the theoretical part, coordinate measuring machines were discussed with emphasis on multisensor measuring machines. The practical part is focused on the evaluation of measured values of components on the CMM SOL 311 according to the standard ČSN EN ISO 14253-1: 2018.

Evaluation of Surface Texture Profile Parameters and Verifying of Conformity with the Specification in the Drawing
Kupský, David ; Jankových, Róbert (referee) ; Sámelová, Vendula (advisor)
The first part of the thesis is devoted to the development of the current state of knowledge in the field of surface texture assessment using the profile method. The next part is the analysis of the problem and the proposal of a solution for the evaluation of surface texture with the consideration of measurement uncertainties in accordance with the ISO GPS system. Proposal of measurement and evaluation of the given sample was carried out for the demonstration. The measurement was started using a contact profilometer and then the profile parameters were calculated in the TalyProfile Lite software. Three different specifications were chosen for the calculated geometric parameters to outline all the possibilities that can arise when determining compliance with the specification. The proposal with consideration of uncertainties was compared with the evaluation method according to ČSN EN 4288 and from that were deducated conclusions and recommendations.
