Finishing milling of accurate surface
Šimonek, Ondřej ; Kalivoda, Milan (referee) ; Osička, Karel (advisor)
The aim of this work is to find a suitable cutting tool and suitable cutting conditions for the production of hydrostatic surfaces of a crossmember with the quality of the surface structure of Ra 0.8 mm. The technology described in the thesis deals with finishing hydrostatic surfaces by milling, with the quality of the surface structure of Ra 0.8mm. As the production method cutting operations using CNC machines is used. To assure the quality of the surface insert tools are used, which are selected and evaluated based on experimental testing from six different suppliers. The technological process of production solves the problem of the hydrostatic surface production from the first gripping all the way to the final manufacture of the surfaces.

New methods for inner rotary surfaces finishing
Kazdera, Tomáš ; Zemčík, Oskar (referee) ; Zemčík, Oskar (advisor)
Content of the text deals with the methods of finalizing the internal surfaces of revolution. The paper discussed the theory most widely used machining methods that are commonly used in engineering practice. For each methods, are given the tools achieved surface roughness and geometric tolerances. The instruments are assigned to the machine on which the finishing operations are undertaken.

New methods for outer rotary surfaces finishing.
Bartošík, Luděk ; Janský, Milan (referee) ; Zemčík, Oskar (advisor)
This bachelor thesis deal with technologies of finishing rotate surfaces, describe individual methods, their advantages and disadvantages and results on quality of surface. It describe older and new technologies and too conventional and unconventional methods. Here is overview of most used and best know technologies in present engineering.
