Educational tasks for teaching of geometric tolerances
Hanáček, Lukáš ; Foltýnová, Dana (referee) ; Svoboda, Petr (advisor)
The bachelor’s thesis is divided into two main parts. The first one is a theoretical part and it clarifies the basics of geometric tolerancing. The second one is practical and it uses the knowledge gained from the first part to show how geometric tolerances are measured and evaluated. It is demonstrated on a part made especially for the thesis. The measurement uses a device available at the faculty. The purpose of this work is to educatively illustrate the measurement and evaluation of the specifications to students.

Evaluation of geometric tolerances using 3D optical digitization
Veik, Matouš ; Zatočilová, Aneta (referee) ; Koutecký, Tomáš (advisor)
Bachelor‘s thesis deals with evaluation of geometric tolerances on models obtained by 3D optical digitization. In the first part is analyzed problematics of optical digitization in the field of standardization of optical systems. Another part of the bachelor thesis describes the process of evaluation of geometric specifications. The goal of this work is to compare the evaluation of geometrical tolerances according to ISO and ASME standards and their applications in GOM Inspect software.

Quality assurance of mechanical shaft seal assemblies
Příkaský, Jakub ; Maradová, Karla (referee) ; Jankových, Róbert (advisor)
The thesis deals with the issue of a selected sealing shaft assembly. On this assembly, a nonconformity analysis was performed and corrective measures were proposed, applied and verified in a subsequent PDCA cycle. Furthermore, realistic improvements have been proposed that can have a significant positive impact on the overall quality of this shaft seal assembly in the future. The main contribution of this thesis is to reduce the number of non-conformances and on top of that to deepen the management of modern quality methods in the collaborating organization.

Building and control of 5-axis milling machines
Hekrle, Pavel ; Marek, Tomáš (referee) ; Holub, Michal (advisor)
This bachelor thesis deals with detailed description of acceptance tests of machining centers. The first part contains segmentation of geometric tolerances, which are used for geometric accuracy tests. A large part of this thesis is dedicated to these tests. The next part includes phases of preparations for acceptance tests as well as segmentation and progress of these tests. One part of the thesis is devoted to machine alignment. The last chapter contains detailed description and principle of some modern measuring devices which are used for acceptance tests.

Multiparametric diagnostics of high-speed machine
Bowyer, Matouš ; Harčarík, Matej (referee) ; Jankových, Róbert (advisor)
The goal of the thesis was applying multiparametric diagnostics to determine the state and wear of a high-speed milling machine. In the theoretical section, selected areas of multiparametric diagnostics have been described as well as a significant focus on vibrodiagnostics. The chosen methods for the practical section were incorporated into the group “metrological diagnostics”. Several different types of measurements have been performed on the designed test piece. The measurements were analyzed and lead to these specific results: a drawing of the test piece, a structured methodology for evaluating the test piece, recommendations for diagnostics of the specific machine, and proposals for the future development of the field of metrological diagnostics.

Methods of workpieces measurement
Verevkina, Aleksandra ; Šrámek, Jan (referee) ; Marek, Tomáš (advisor)
This bachelor's thesis focuses on the measurement of geometric tolerances of workpieces.In the first part, international ISO GPS standards, terminology from the metrological dictionary and used measuring devices are examined. In the practical part, comparative tests for three measuring devices and analysis of the obtained results are carried out.

Creation of educational animation for teaching geometric tolerances
Doležalová, Denisa ; Koutecký, Tomáš (referee) ; Foltýnová, Dana (advisor)
This bachelor’s thesis is made out of two parts. First part consists of overview of basic geometrical tolerances, which include their markings, principles and other aspects including basic concepts which fall under norm ČSN EN ISO 1101. Second part is practical, it describes five tasks created for education of geometrical tolerances. Attachment of this thesis includes educational task in form of videos displayed in 3D. Animations show marking of modeled geometrical tolerations, explaining their basic principles and in some cases show ways of their evaluations.
