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.

Modern methods in spur gearing production.
Kopečný, Libor ; Zemčík, Oskar (referee) ; Zemčík, Oskar (advisor)
The division and comparison of modern methods of production of spur gearings. The introduction is focused on the characteristics and description of cog wheels. Furthermore, the types of gearing and gear mechanisms are introduced. The main part of the text deals with individual ways of a production of spur gearings including finishing methods. The following part of this work describes the importance and possibilities of heat and chemical-heat gearing production. In the last chapters, the evaluation and achieved results of individual technologies of gearing production are introduced.

New advanced milling tools
Dočekal, Petr ; Dvořák, Jaromír (referee) ; Humár, Anton (advisor)
This bachelor thesis deals with the subject of milling and relevant devices. The first part introduces the essential data about milling, the information necessary for specification of the cutting conditions and the form of milling. It also provides the description of types and labelling of milling machines. The second section centres on the milling device assortment of three companies, specifically on slab mills by WALTER AG, Sandvik Coro-mant, Pramet Tools, s.r.o. The final part of the thesis comments upon the rec-ommended usage scope of the machinery produced by the companies men-tioned above.
