Technology solution of "konzola" component in condition of a small firm
Štegnerová, Kateřina ; Slaný, Martin (referee) ; Kalivoda, Milan (advisor)
This work deals with the solution technology component of the console. There is an evaluation of technological principles, functionality and the suggestion of optimize. Stock, machines, tools and gauges for each operation are selected according to conditions of the company. For each operation are determined cutting conditions and production time. There are two versions of the production process. Additionally these two versions are evaluated. The console is also analyzed in terms of stress-strain relations, finite elements, which appear critical points. In conclusion, these results are judged.

Manufacturing possibilities of sparking plug body
Strnad, Miroslav ; Kopřiva, Miloslav (referee) ; Podaný, Kamil (advisor)
Difficulties of manufacturing sparking plug body are analyzed in this thesis, which aims to select the most appropriate option. Body is circular section of steel 1.1191 (12 050), with a hole in the middle and upper part of this body is ended with hexagonal shape. The series is estimated at 1 000 000 units per year. For the production of sparking plug body are selected options from the machining and forming technologies. Specifically, turning and milling, casting, forging, a method using superplastic material and cold extrusion. Selected technologies will be reviewed based on cost to produce one piece, time requirements of manufacture of the unit, material usability and overall feasibility. According to these parameters forming is chosen as the best option.

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.

Analysis and usage of form cutters.
Vašíček, Jiří ; Zemčík, Oskar (referee) ; Zemčík, Oskar (advisor)
This work is a summary description of form cutters. It explains the basic definition of cutting and the principle of milling process, with a description of stock removal and basic cutting conditions. It includes characteristics and distribution of milling tools according to their shape and construction and a more detailed description of milling cutters and the most widely used clamping devices. The end of this thesis is devoted to comparing of chosen solid and form cutters with indexable inserts from major producers, like companies ZPS- FN Inc., L.M.T . Fette Ltd., AB Seco Tools and Mitsubishi Materials Corporation.
