Milling cutters for CNC machine tools
Janošek, Martin ; Sámelová, Vendula (referee) ; Humár, Anton (advisor)
My bachelor thesis is about milling cutters for CNC machine tools. First the thesis deals with milling theory. There are fission tools or fission machines. Next chapter is about holding tools. The practical part deals with an assortment of production of milling tools for milling flat surfaces made by three milling tools producers. These are Sandvik Coromant, Pramet Tools and Walter companies. In the end of my work these companies are evaluated from different points of view.

Cold recycling of flexible pavements
Řehulka, Martin ; Koudelka, Tomáš (referee) ; Varaus, Michal (advisor)
The bachelor´s thesis is focused on recycling of the flexible pavements in general, namely cold recycling. This modern technology was introduced in the Czech Republic after 1989. The first half of the thesis describes theoretically various types of recycling of flexible pavements, where the greatest attention is paid to this technology. The second part describes the section of the modernization D1 motorway where this cold recycling was applied. The technological process, including visual documentation and control tests, is documented.

A new manufacturing technology for an automotive part
Kotrsal, Miloš ; Polzer, Aleš (referee) ; Píška, Miroslav (advisor)
The thesis is about analyzing a current technological process. It also includes describing a current production machines, tools and methods of measuring. The problems of milling procedure are described in a detail. In addition, there are descriptions of a technology of the production, methods of using production preparations, and methods of measuring gained results. There is designed an innovative solution of a new technological production. A history of the stoba Precizní Technika Inc. is summarized there. A comparison of the two versions is described in a techno-economic evaluation part, which is about comparing of mechanical time. A solution of the thesis is realized in a medium-sized production company during particular conditions. Limited conditions of the thesis are influenced by the conditions of the selected company.
