Design of automatic clamping device for CNC milling machine
 Jirásek, Jiří ; Holub, Michal (referee) ; Tůma, Jiří (advisor)
This work is focused on the design and construction of a device for automatic replacement of workpieces for CNC milling machines. The thesis contains research in the field of automatic replacement of workpieces. The design itself can be divided into two parts. The first part is the selection of a universal clamping platform and the design of a technological pallet. The second part is the design and construction of the clamping device. First, different design variants are proposed.. These variants are then evaluated by multi-criteria analysis, based on which the most suitable variant is chosen. This is followed by the selection of suitable components for the assembly of the universal clamping platform and the construction of the technological pallet. The main part of the work is the structural design of the pneumatic wedge vice, including the necessary calculations and design of individual components. The output is technical drawings of chosen components and a technical drawing and CAD model of the assembly.

Advantages and disadvantages of clamping the workpiece with zero points
 Jirků, Kateřina ; Tůma, Jiří (referee) ; Knoflíček, Radek (advisor)
This bachelor's thesis deals with a technical-economic analysis of whether the purchase of zero point clamping system is economical. It compares the advantages of the zero point system both to standard clamping devices and to each other. It also compares brands and their dealers to the Czech Republic. Finally, this technology is evaluated by calculating the return after the application of zero point clamping system on shop floors of Soma Ltd based in Lanškroun.
