Design of a upright drilling machine
Matoušek, Kamil ; Bilík, Martin (referee) ; Blecha, Petr (advisor)
The subject of this thesis is to propose a design of an upright drilling machine. The upright drilling machine is described in the first part. Research about machines available on the market nowadays is accomplished in the second part of the thesis. Based on this research the parameters of machine are selected in the final part and proposal of the engineering design of an upright drilling machine. Basic construction calculations are made too. The result of this thesis is an assembly drawing and a 3D model of an upright drilling machine.

Superhard cutting materials and theirs effective use
Stradějová, Alena ; Madaj, Martin (referee) ; Humár, Anton (advisor)
The master’s thesis is aimed at superhard cutting materials (polycrystalline diamond and polycrystalline cubic boron nitride) and their effective utilization. It describes the characteristics and production of these materials and evaluates product ranges of the most significant producers of tools and tool materials in given area. It further compares working conditions of selected world's producers which are related to the growing utilization of these materials in machining process. The thesis also deals with the cutting power of tools and provides a technical-economic assessment of the discussed issue.

Superhard cutting materials and their effective use
Teplý, Radek ; Sedlák, Josef (referee) ; Humár, Anton (advisor)
Diploma thesis is focused on the superhard cutting materials (polycrystalline diamond, polycrystalline boron nitride) and presents their physico-mechanical properties, production, efficient use, new trends. It assesses the range of cutting tool materials and individual front world producers in terms of optimum cutting conditions for turning operations and type of material to be machined. Further, these cutting materials are compared between different manufacturers to bring out thein differences in cutting conditions.

Drilling technology solution in the maintenance center of small firms
Huňáček, František ; Mouralová, Kateřina (referee) ; Kalivoda, Milan (advisor)
The basic characteristics of the drilling technology, view of tools for drilling, descriptions of the parts and angles of twist drill are described in the first part of this project. In the second part of this project there are descriptions of various drilling technologies, the choice of cutting conditions and the choice of cooling and lubricating emulsions and oils. The range of tools, machinery and clamping equipment in the workshop machinery maintenance sugar factory in České Meziříčí are described in the next part of the project. Also specific technological conditions for the production of precision holes (with a use of a calculator) was determinated. After that their production was performed. In the end the possibilities of production machinery maintenance workshops during production of holes using drilling tools are shortly valorized.

Production Concept of Front Wheel Hub Carrier for Formula TU Brno Racing
Torčík, Václav ; Jaroš, Aleš (referee) ; Sedlák, Josef (advisor)
This thesis deals with manufacturing process of a front wheel hub carrier prototype for formula TU Brno Racing Dragon 5 series. The paper starts on foregoing work of design team leading to a proposed model and material. Both material and model are investigated form a manufacturing point of view. Cutting conditions and milling strategy are proposed based on final product analysis. Prototype was manufactured on CNC machining centre MCV 754 QUICK in company BOSCH DIESEL s.r.o. in Jihlava. Retrospective analysis of performed manufacturing process and critical risks is provided with a proposal of more effective manufacturing process. In the closure, there is technical-economical evaluation of chosen manufacture done by milling. Alternative manufacturing options including 3D print and welding are compared in technics and costs.
