Design of multi-functional machining centre
Gruník, Jan ; Holub, Michal (referee) ; Blecha, Petr (advisor)
This work deals with the construction and describes a detailed calculation of a machine frame of the shaft-turning lathe and 2D axis passes including the underpass according to the chosen initial parameters. The information contained in this work is not only of theoretical knowledge, but it should also serve for the practical use as a guide for the frames construction. The work also contains a background research on the topic, the model frame, the frame strength analysis, optimization of the frame, 2D axis, calculation, design and implementation of the underpass and the whole assembly. A suggestion for the future procedure and optimizing of the existing structure is found in this work as well.

Construction of equipment for deburring gears
Bosák, Daniel ; Tůma, Jiří (referee) ; Holub, Michal (advisor)
This thesis deals with the design of the equipment for deburring gears on the Gleason GP 200 machine. The first part contains research of current methods of deburring. At the following analysis of the task dimensions and layout of the machine, focusing on equipment placement, are analyzed. Next, a choice of tool is made. Two variants of design solutions are outlined. One of them is more elaborated. Important structural units are solved. At the end of the thesis an analysis of the geometry and stiffness is made. The maximum equipment load is recommended with regard to the maximum deformation.

Design optimisation and strenght checking of Water tiltable devices
Mach, Jan ; Holub, Michal (referee) ; Knoflíček, Radek (advisor)
This master’s thesis is about possibility of fruit and vegetable process from agricultural raw material to food. The first part of thesis include information about machinery, devices and process line and describe how this devices work. The second part solve water tiltable device, this part explain what water tiltable device do, how work and describe structure of each subassembly. Next step solve the device by kinematics aspect and aspect of load analysis. Calculation is included in annex one. Results of annex one are used for FEM (finite element method) simulation of frame. Output of FEM simulation can be used for finding safety factor of displacement and strain, output data are used for optimization of device.

Desing of PKS type TRIPOD
Coufal, Jiří ; Knoflíček, Radek (referee) ; Holub, Michal (advisor)
The thesis acquaints the reader with issues of manipulators based on parallel kinematic structures. It includes also the description of the construction procedure of chosen mechanism. Introductory search part specifies selected terms relating to building elements and describes their requirements. Alternatives of construction and used types of manipulators are shown in the illustrative images with labels. Next chapters deal with projects of selected parallel mechanism and methodologies of constructions. These chapters describe the design of all devised construction nodes. The construction and testing of the produced prototype is properly documented, indicating the resulting knowledge.

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.
