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.

Design of milling machine spindle
Švarc, Marek ; Pavlík, Jan (referee) ; Blecha, Petr (advisor)
This bachelor's thesis deals with solving design of milling machine spindle. At first, the background research in milling machines and their spindles is processed. Here is adduced distribution of machines, basic description and examples from current manufacturers. In this part, there are described types of spindles and their basic parts. Second part of thesis is focused on technical calculations and design of the spindle based on defined parameters. An attachment includes assembly drawing, three main parts drawings and 3D model of spindle.

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.

NC control system on Beckhoff platform
Jelínek, Pavel ; Bradáč, František (referee) ; Vetiška, Jan (advisor)
This thesis deals with a creation of a control system of 3-axis milling machine. The beginning of the thesis is dedicated to the general description of the problematic of the numerically controlled machines and the technologies used in this branch. The next chapter describes mechanical and electronical adjustments of the machine. Following chapters are dedicated to the creation of PLC program and HMI using the TwinCAT software. In conclusion, this thesis deals with commissioning of the machine, measuring its geometrical accuracy and testing.
