Technological aspects of tools for wood machining
Brlica, Vlastimil ; Humár, Anton (referee) ; Prokop, Jaroslav (advisor)
The fully fashioned master’s thesis within the frame of the master’s study at the Fakulty of mechanical engineering deals with subject woodworking tools. There are characteristics of wood and tool materials used for woodworking. There is an emphasis on milling cutter in each case of construction of selected woodworking tools. Whereas there is concrete proposal of milling cutter used for production of half round profile – half round concave cutter – at the end of the thesis.

Cutting operation of cast iron
Nejedlý, Zdeněk ; Jaroš, Aleš (referee) ; Kalivoda, Milan (advisor)
Bachelor thesis deals with cutting operation of alloys of iron with high level of carbon – cast iron. First part of the thesis deals with properties of these materials. This part is focused on production, chemical composition and form of carbon, which are aspects that influence properties and machinability of cast iron. Differences in individual types are resumed in chapter, which deals with distribution of cast iron. Second part is devoted to machining. Machinability is evaluated for each group of cast iron and individual parts devotes to tool materials, wear of the tool edge and cutting surround.

Cutting ceramics and its effective use
Kavalír, Vít ; Sedlák, Josef (referee) ; Humár, Anton (advisor)
Master’s thesis are concerned with the cutting ceramic materials and its ef-fective usage. The first part of the thesis is focused on the general properties of the cutting ceramics, its history, development, production and description of the various types. This part includes as well a description of the mechanic-physical properties and the potential of the usage for machining. The second part of the work solves the general evaluation of the cutting power. The main issue in the next part is the identification of cutting ceramics range and the selection accor-ding to main world producers. The fourth part deals with the assessments and the comparison of the working conditions for different types of the machined ma-terials. The technical economic assessment shows the potentials in the total pro-duction costs reduction.

High-Speed Steel Mills with PVD coatings and their Use
Žilák, Marek ; Fiala, Zdeněk (referee) ; Jaroš, Aleš (advisor)
This bachelor thesis "Mills from high-speed steel with PVD coatings and their use" deals with tool materials and their distribution (mainly high-speed steel). The problem of high-speed steels is analyzed (their distribution, properties and uses, chemical composition and finally heat treatment). Then the characteristics of the coating methods (mainly PVD) is analyzed. The conclusion of this work is focused on the types of spray coating and the responsibility of the high speed steel mills and their use in current practice.
