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.

Measurement of geometric accuracy of machine tools
Nakládalová, Tereza ; Zahálka, Jiří (referee) ; Knobloch, Josef (advisor)
In this bachelor thesis the measurement of geometric accuracy of machine tools is described. The measurement of circle interpolation is implemented and the results are evaluated. The theoretic part deals with sources of error origin and accuracy division according to affecting factors. Further, the geometric errors are analyzed and determination of basic methods outlined. The next part of this work describes different kinds of current measuring devices and their principles of testing. For approaching the volumetric accuracy of machine tool other methods are discussed. The experimental part deals with testing the machine tool and result evaluation for each working plain and whole workplace. In conclusion, the particular measurements with varying input testing parameter are compared.

Workpiece geometrical accuracy measurement possibilities
Tvardek, Michal ; Musil, Martin (referee) ; Blecha, Petr (advisor)
The aim of this bachelor thesis is to do a research in the field of measurement of geometrical accuracy of workpiece. In the introduction I deal with the description and graphic interpretation of geometrical tolerances and parameters of the surface texture, including their illustration in the drawing documentation. Then I briefly summarized the major measuring methods of the chosen geometrical features and gear wheels. I also described the current equipment for measuring geometrical accuracy and surface texture for both inprocess and postprocess usage; meanwhile I tried to accentuate their main features and advantages.
