Superhard cutting materials and theirs effective use
Vampola, Lukáš ; Sedlák, Josef (referee) ; Humár, Anton (advisor)
Diploma thesis is focused on cutting superhard materials (polycrystalline diamond and polycrystalline cubic boron nitride). It deals with physical, mechanical and cutting properties, production and effective use. Evaluative product range of superhard cutting materials of the prominent world producers in terms of cutting conditions and type of materials machined in turning.

Cutting ceramics and its effective use
Podešva, Lukáš ; Dvořáková, Jana (referee) ; Humár, Anton (advisor)
In the first part of this diploma thesis there are discribed basic findings about cutting ceramics (sorts, notation, structure, physical-mechanical properties, using, production) and it evaluates this tool material from the aspect of cutting power. The second part focuses on complex data processing about assortment of ceramics cutting materials of significant tool materials producers and comparison of service conditions (kind of mechanided materials, cutting conditions), which are recommend for effective turning by producers.

Tools for CNC milling centres
Konečný, Petr ; Madaj, Martin (referee) ; Humár, Anton (advisor)
This thesis is focused on milling tools for CNC milling centers. The first chapter of this thesis deals with a short theory of milling and the characteristics of CNC milling center. In next chapter are divided and described milling tools in terms of use and construction. This chapter also describes tool materials, clamping, coating and marking of these tools. The practical part is devoted to production assortment of mills from major producers. It is an analysis, description and evaluation of assortments of these producers. For this purpose were selected companies Sandvik Coromant and Pramet Tools.

Solution wear of tool with inserts in condition technology of turning.
Kružík, Petr ; Humár, Anton (referee) ; Kalivoda, Milan (advisor)
This bachelor thesis analyzes wear occurrence at chosen tool inserts in the process of turning of a heat treated cylindrical workpiece. Inserts for turning have been chosen from the area of coated and non-coated cemented carbides and cermets with respect to the used type of workpiece material. The work further deals with the possibility of their use under cutting conditions that are set to the upper cutting limits from the recommended range, especially without cooling. To obtain detailed information, the conditions of the test are further modified. Then, the results are also evaluated from the point of view of costs, i.e. market prices of inserts for possible application in the manufacturing process.

Solution milling with CNC machine.
Chlup, Martin ; Madaj, Martin (referee) ; Kalivoda, Milan (advisor)
Bachelor´s thesis includes the solution of production technology of the motor´s stator. It also solves the problem of substitutive production when the serious production is stopped. Technology of series production was used by company Hanakov, inc. It also refers to functional possibilities of tools and machines at shaping the motor´s stator.
