On the production technology of a shaped part with multi-axis machining
Kopcík, Daniel ; Polzer, Aleš (referee) ; Píška, Miroslav (advisor)
The theoretical part of this thesis is introducing basic information in production of shaped components on CNC machines. It describes each steps from a design of the component to production. Main target is summarization of available modern technologies that can be used. Experimental part uses these modern technologies for processing design shaped component. It describes process of design 3D model part in CAD system, subsequently creation of program for machining in CAM system and solves production of part on CNC machine. The aim of this thesis is design part with interesting design and production difficult enough to represent company, where it was made.

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.

Využití půdních rotačních fréz s horizontální osou rotace v zemědělství a lesnictví
NĚMEČKOVÁ, Michaela
The aim of the work was to verify the performance and design working quality performance of rotary milling machines with horizontal axis of rotation in artificial forest regeneration, support of natural forest regeneration in selected forest stands and in agriculture with different soil and terrain conditions. The measurement was carried out on four different carrier cutters, each machine carrying a different soil milling machine. Measurements took place in various environments as well as soil types, crops or quality requirements for the work performed. In this work are compared performance of given carriers, in terms of aggregation with individual models of milling machines. The tables show the most important parameters such as average fuel consumption, average area efficiency and fuel consumption to area efficiency. Furthermore, there is an evaluation of the quality of the work done.

Cold recycling of flexible pavements
Řehulka, Martin ; Koudelka, Tomáš (referee) ; Varaus, Michal (advisor)
The bachelor´s thesis is focused on recycling of the flexible pavements in general, namely cold recycling. This modern technology was introduced in the Czech Republic after 1989. The first half of the thesis describes theoretically various types of recycling of flexible pavements, where the greatest attention is paid to this technology. The second part describes the section of the modernization D1 motorway where this cold recycling was applied. The technological process, including visual documentation and control tests, is documented.

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.

Výroba desek plošných spojů pomocí CNC zařízení s využitím Open Source nástrojů
HOUŠŤ, Milan
This bachelor thesis aims to describe the production process of prototype and small series printed circuit boards on a computer numerically controlled (CNC) milling machine, and to document a practical reproducible working procedure using CAD-to-CAM files and open source tools to create a CNC control file. In the analysis section the results of the proposed procedures will be presented using a specific printed circuit board as example.
