Machining of components on CNC machines
Osička, Petr ; Mouralová, Kateřina (referee) ; Kalivoda, Milan (advisor)
The bachelor thesis deals with the manufactory of the rotor for the electric motor on the CNC lathe. The first part describes the function and design of manufactured constituent part. The next chapter designes and describes production process of machining the shaft and next steps of manufactory are described. They basic production capacity calculations are made. In the next part the NC program is designed, which is used to manufacture the shaft as a model product.

Design of magnetic drilling machine
Jun, Lukáš ; Tůma, Zdeněk (referee) ; Tůma, Jiří (advisor)
The thesis is focused on a specific type of drilling machines, the magnetic drills press. These machines are typical for their magnetic base and are used mainly to machine magnetic materials, nonetheless, with suitable accessories, also the non-magnetic materials can be machined. The first part of the thesis begins with a description of the individual parts of the magnetic drill, their types and an overview of the accessories. The second part of the thesis contains the design of the drill itself. Cutting conditions for a 20mm twist drill and a 60mm annular cutter are defined. Based on the cutting conditions the motor is selected, then the design of a gearbox, selection of bearings and the whole assembly of the gearbox is described. Calculations of gearing, 3d model, drawing of assembly and two parts are attached with the thesis.

Pallet Feeder of the Machine Tool Centre
Krenželok, Andrzej ; TOSHULIN, Jaroslav SKLENÁŘ, (referee) ; Novotný, Lubomír (advisor)
The subject of this thesis is the proposal of constructional solution for pallet changer of the vertical machining center. This pallet changer serves for the manipulation with technological pallets between dilatory places of the machining center and charger of pallets. Thanks to this changer the machines share one workpieces´ base. Main accent is not put only on the function but also on the low price of this solution.

Pneumobile dynamometer design
Fritscher, Matyáš ; Kubík, Michal (referee) ; Jeniš, Filip (advisor)
This bachelor thesis concerns design of measuring station with a dynamometer for a racing pneumobile developed by a student team. The aim of this device is to simplify the process of tuning of the vehicle and to make it more precise. At the beginning of the work, there is a research of current commercial solutions of dynamometer stations. Then, while choosing a suitable brake, there is an evaluation of the possibility of repurposing an old brake, given by the university for this project. After verifying that it meets the necessary requirements, there are several concept solutions presented. For the selected concept, with a specific design for this vehicle, there is a complete design solution including safety analysis of selected nodes.
