Small CNC machine
Moštěk, Jiří ; Matěj, Zdeněk (referee) ; Záplata, Filip (advisor)
This diploma thesis deals with the design and construction of a three-axis CNC machine primarily designed for PCB drilling and production of front panels for various electronic devices. All three axes are driven by stepper motors NEMA 23 which are connected to stepper motor drivers L6470. Processor STM32F407 is used to control the whole machine. The wiring is completed by a LCD display with touchscreen which is used to communicate with user. Data for drilling can be entering manually or via USB inerface. Part of this thesis is the selection of a suitable construction and components, assembling equipment, wiring design of electronic circuits and writing the code to control the machine. Finally, the parameters of the designed device have been measured.

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.

Welding manipulator construction design
Fuks, Šimon ; Tůma, Zdeněk (referee) ; Štěpánek, Vojtěch (advisor)
This bachelor thesis deals with the design of a five-axis welding manipulator as an additional device to a welding table. The research focuses on knowledge from arc welding automation, especially on the use of industrial robots and manipulators in this area. A rich selection of accessories for robotic arc welding is also summarized. In the practical part, several conceptual variants are proposed, and the most suitable variant is further developed. The basic technical calculations of the manipulator are presented and the individual construction details are discussed. Furthermore, the work deals with the safety and control possibilities of the designed manipulator. The work also includes a drawing of the overall assembly.

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 milling table for machining wooden boards
Uhlíř, Radim ; Mazal, Pavel (referee) ; Čípek, Pavel (advisor)
The bachelor's thesis deals with the design and implementation of a milling table for machining wooden boards. In the research part, an analysis of the solutions available on the market was performed together with an analysis of workpiece fixtures, hand milling fixtures and linear guides. Based on the research, two conceptual solutions and several variants of structural nodes were proposed. The most suitable constructional solution was selected from the conceptual solutions, calculations of critical nodes were performed and drawing documentation was made. Subsequently, a prototype of the table was made and its functionality was tested. The table can clamp and machine a wooden board with maximum dimensions of 1000 x 800 x 100 mm.

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.
