Design of linear axis for heavy machine tool
Kubálek, Petr ; Marek, Jiří (referee) ; Hermanský, Dominik (advisor)
This diploma thesis deals with the design of the linear axis of a heavy machine tool. It describes the basic specifications of these machines, their manufacturers, the parts of which the axis consists and the design itself. The design includes several design variants, calculation of the movement mechanism, drive and linear guide. Follows the selection of the most suitable variant and the drawing documentation of the resulting linear axis.

A design of engraving plotter
Brtník, Vojtěch ; Tůma, Zdeněk (referee) ; Tůma, Jiří (advisor)
This bachelor thesis, in addition to the actual design of the laser engraving laser, contains basic information about laser engraving technology and marking used in industry. It explains the physical principle of the laser and the laser source, which is essential to understand and classify laser modules. Provides an up-to-date market survey of the laser engraving modules and engraving plotters in use. In the design part, the design of an engraving plotter for SMC company is carried out using 3D models in Solidworks 2022 according to the specified parameters. The plotter design includes the selection of a suitable linear motion unit with electric drive, the assumed control, control calculations and the design of the plotter structural elements. The next section deals with the design of the support part and includes safety and functional elements. The paper concludes with a cost evaluation and recommendations for practice.

Hobby milling machine design
Valášek, Ondřej ; Zemčík, Oskar (referee) ; Dvořák, Jaromír (advisor)
At the introductory part, this thesis deals with description of individual parts of construction and control of CNC machine. Individual parts are described by vievpoint of principle of function, attributes and possibility of implementation on hobby machine. Furthermore is performed brief analysis of commercially manufactured CNC milling machines, which can be purchased on domestic and foreing markets for a purpose of milling wood and eventally aluminuum alloys. Main purpose of thesis is custom desing of CNC milling machine for non-commercial use. Three draft proposals are created first. Then one of them is developen into complete proposal. This design is then subjected to numerical simulation to pre-determine the machine's stiffness and ability to milling aluminium. The result of this simulation confirms the possible use of the machine for milling aluminium alloys. According to the simulation, the maximum deformation for possible machining of aluminium under predetermined conditions is 0.18 mm. In the last part of the work a price calculation was made, determining the approximate cost of the machine production at 75 000 CZK. The work includes a complete drawing documentation of the mechanical parts of the machine.

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.

Design of small hobby CNC milling machine with fixed table
Hanzal, Jiří ; Marek, Tomáš (referee) ; Pavlík, Jan (advisor)
The topic of this work is the design of a small model CNC milling machine with a fixed table for machining wood, plastic, or light alloys (Al, Zn, etc.). It also includes a calculation report and drawing documentation of selected nodes. The beginning of this work consists of an introduction to the issue of milling machines, their distribution and subsequent market analysis. Subsequently, the input parameters are designed on the basis of market analysis and in the last part there is a calculation report, the design of the milling machine itself and a short economic evaluation.
