Technology of production combinated cutting tools
Rusz, Radek ; Kalivoda, Milan (referee) ; Osička, Karel (advisor)
In the thesis is solved manufacturing technology of step drill from material of cemented carbide. At first is made review of existing shank cutting tool types, after that follows an analysis of cemented carbide tool material. In the next part of thesis is manufacturing technology of this tool, including review of grinding wheels, designed. Output of this work is procedure of program designing for manufacturing this tool in software Numroto. Next output is techno-economic evaluation of step hole manufacture with combined tool and comparison to conventional type of manufacture.

Cutting forces when drilling fibre reinforced composites
Režný, Tomáš ; Sedlák, Josef (referee) ; Humár, Anton (advisor)
This master´s thesis is focused on fibre–filled composite materials, their distribution, labeling, usage, development and production. The aim of this work is complex processing of acquired technical knowledge, and evaluation of technological rehearsals of drilling composite materials which are reinforced by glas fiber and prepreg in terms of the impact of the machined material, wor-king conditions and the tool, and its wear to the feed force value and torque.

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.

On the production of a shaft for agricultural machinery drive
Tenora, Tomáš ; Prokop, Jaroslav (referee) ; Píška, Miroslav (advisor)
The subject of the assigned bachelor’s thesis is to analyse the production technology for shaft agricultural machinery drive. After analysing the technical documentation, the thesis includes the analysis of current production conditions in the company. The main goal of the thesis is to design a technology of components, specified in terms of more efficient production, which includes six alternative technologies in total. Sub-variants are calculated and graphically displayed. To innovate the production process there are recommended variants of usage of multi-machine operator, change of machine tools and change of technological processes. Thanks to it the significant cost savings are achieved.
