Design of the PKD cutting edge cutter
Křehlík, Luboš ; Trčka, Tomáš (referee) ; Polzer, Aleš (advisor)
The thesis deals with the design, construction, production and testing of cutters with polycrystalline diamond cutting edges. Polycrystalline diamond is a suitable cutting material for machining very abrasive materials such as aluminum alloys or composite materials. The design of the tool is focused on the application of the chip breaker on the front of the tool. The aim of the solution is to reduce the cutting force in the machining of the aluminum alloy used in the aerospace industry. The first part of the thesis deals with problems related to milling technology. The practical part describes the design and construction of prototype cutting tools. Three tools were designed for experimental measurement. The technology of cutting tools made from super hardened cutting materials with laser technology is presented. The experimental part of the thesis is a measurement of the cutting force according to cutting parameters and machined material.

A new Variant of Production Components "Sole Plate"
Briš, Tomáš ; Osička, Karel (referee) ; Kalivoda, Milan (advisor)
The bachelor thesis aims at forming a new variant of production components „sole plate“ which has a character of a flat block with stepped protrusions. The main points of the work will be component analysis, description of the conditions under which the solution was carried out, description of the current technology, proposal of a new technology as well as their final comparison and the results assessment. The work is focused on forming a more effective manufacturing process which would replace the current one.

A universal milling machine with the 4th axis controlled by a divider
Chladil, Jan ; Fiala, Zdeněk (referee) ; Kalivoda, Milan (advisor)
The bachelor thesis deals with types and facilities of applying the dividing head on the universal milling machines. Basic types of milling machines and ways of dividing are introduced. The topic includes types of cutting tools which are often used together with the dividing head and the universal milling machine. Appropriate cases in which it is possible to use the dividing head these days are presented, sometimes in connection with computer numerical control machines. The process of angular rotation of a workpiece is illustrated on a shaft during production of straight-sided splines on the universal milling machine.

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.

Model of surface profile after milling operation with plain milling cutter
Horváth, Ľudovít ; Kubík, Roman (referee) ; Zemčík, Oskar (advisor)
In the teoretical part of the master´s thesis, the master´s thesis deals with milling and surface profile describing. In the practical part, the master´s thesis deal with model of surface profile after milling operation with plain milling cetter. For evalution were used data obtained from the computer model of the surface profil and data obtained from measuring the actual surface profil, which was created by machining the material mills with a diameter of 45 mm.
