Design and analysis of the cross table
Zemčík, Matěj ; Pavlík, Jan (referee) ; Tůma, Jiří (advisor)
This thesis deals with the design of the cross table. That is, designing a linear guide, a ball screw and a motor. In addition, dynamic simulations are used in the MSC Adams for machining cycle and the positioning cycle of the semi-product at rapid traverse. As a simulation output are the „real“ load patterns of the bearings in the placing of the ball screws and the durability of these bearings.

Design of linear axis for heavy machine tool
Göbel, Lukáš ; Marek, Jiří (referee) ; Hermanský, Dominik (advisor)
The content of this thesis is the description the various component of the linear feed axis, which are used in heavy duty machine tools. This describes their features, advantages and disadvantages and on these basics, are selected different appropriate design variants. In the second part of this thesis has been drawn up constructional design of these variants. They were subsequently compared and then was chosen the most ideal one for the designed machine, which is heavy machine tool upper gantry type. The work also includes the 3D CAD model of the final version and drawing documentation.

Design of a camera slider for shooting time-lapse shots with a focus on the object
Koupil, Michael ; Franke, Jakub (referee) ; Koutecký, Tomáš (advisor)
This Bachelor’s thesis deals with the constructional plan and implementation of the camera slider while using a 3D printer and Arduino platform. In theoretical part, there is an analysis of the commonly used camera sliders. Based on this analysis, several variations were prepared, and the most feasible constructional plan was chosen. In practical part, the aforementioned plan was worked out, safety calculations concerning selected nodes were made, as well as the mechanical drawing of the device. A prototype was then built and tested, whether it met all the requirements. The suggested device fulfils all the objectives of the Bachelor’s thesis.

Milling Machine for Machining of Plastics
Frejlich, Tomáš ; Brada, Michal (referee) ; Brandejs, Jan (advisor)
Bachelor thesis deals with the structural design of the longitudinal and transverse feed for the milling of embedded hollow fibers of fixed size used in heat exchangers and the design of these components during milling. The work contains a brief description of the routing, basic milling division and a brief overview of the kinds of lines that are use for machine tools. It als presents an overview of fastenings for easy and quick clamping of milling, individual design variations and optimal solution. The works also includes the drawing of the components and complete set. The results of the Bachelor thesis are used for the Laboratory heat transfer and flow at University of Technology, Faculty of Mechanical Engineering.

Development of a linear stage actuator for UHV STM/AFM
Pavelec, Jiří ; Jiruše, Jaroslav (referee) ; Šikola, Tomáš (advisor)
The aim of this diploma thesis is to develop a linear positioning stage for Ultra High Vacuum (UHV) environment. Simple prototypes of the linear positioning stage were designed and incorporated as part of a multiaxis sample manipulator for a UHV Scanning Tunneling Microscopy / Atomic Force Microscopy (STM/AFM). Different types of position encoders and linear guideways are discussed. Implementation of the homodyne interferometer as an optimization tool for a slip-stick based linear stage is described. Scalar diffraction theory is used to model the diffraction grating optical position encoder behavior.

Literature Review on Track Systems in Field of Machine-Tools
Šváček, Karel ; Michalíček, Michal (referee) ; Holub, Michal (advisor)
The main theme of this thesis is is a description of machine tools slide ways. More and more emphasis is laid on the accuracy of slide ways, because it is among the main parts that influences the exactness of of the mashine and thus the whole making process ass well. Materials that the sliding ways are made of are described here as well as their classification and their use with the CNC machines. The final summary of the thesis contents the evaluation.

Design of a two-axis multi-spindle lathe carriage
Sedlář, Jiří ; Štěpánek, Vojtěch (referee) ; Hadraba, Petr (advisor)
This diploma thesis deals with the design of a two-axis multi-spindle lathe carriage. In the first part, there is made a research, and its aim is to find possible variants of design solutions. After the best rated variant was selected, the thesis further continues with the necessary technical calculations of the main design nodes such as a synchronous servomotor, ball screw, linear guide and bearing. The design itself was carried out with regard to calculations and the resulting model was examined in terms of dynamic stability. The subject of examination was to find the natural frequencies of the assembly and to determine the amplitudes of the oscillations which arise from the harmonic excitation force. Finally, Lobe diagrams for grooving and longitudinal turning operations were drawn.
