Kovařík, Michael ; Osička, Karel (referee) ; Sliwková, Petra (advisor)
This thesis is focused on design of production technology of specified components by machining. To introduce the issue the introductory part of the work is devoted to the description of specified components, that is one-handed axis and metal nut, where emphasis is put on construction technology, options of production and components material. Introductory part is followed by the research part that is the theoretical basis for the practical part. This part of the work is focused on machining technologies – turning, milling and drilling that will be used for the production of specified components, then it deals with tool materials, the chosen surface conditioning and heat treatment. The main part of the thesis is a practical part in which the manufacturing process of the given components is proposed. The manufacturing process is focused on the choice of a suitable blank, machine tool, tools, the way in which the components will be measured and checked, then on the development of production technology and the creation of the NC code in the given control system. In conclusion of the work a technical and economic evaluation of the proposed process is presented.

Manufacturing of grill
Bartáček, Petr ; Císařová, Michaela (referee) ; Podaný, Kamil (advisor)
The task was to design a disassemblable and transportable grill capable of grilling food up to 10 kg with the possibility of easy adding of charcoal. Corrosion-resistant steel 1.4301 was chosen for the material in contact with food, steel 1.0425 for heat-stressed parts, and steel 1.0038 for all other structural parts. The production technology included shearing, cutting, bending, rolling, welding, and machining using the machine park of the Institute of Manufacturing Technology at Brno University of Technology. After comparing the current market, a garden grill was designed with dimensions of 900 mm in length, 625 mm in width, and 1510 mm in height when closed, with a total weight of 78 kg and a sheet thickness of 2 mm. The drive unit, model MOT-EC 15/3-5, was chosen for its performance. The spit with forks was supplied by Kovo Janeček. The total cost of manufacturing the grill was estimated at approximately 10,000 CZK, and its transportability can be achieved using vans or larger vehicles such as SUVs or trailers.

Monitoring of nutritionally imporatnt elements and inorganic contaminants in moravian red wines
Dukát, Dominik ; Trenzová, Kristina (referee) ; Pořízka, Jaromír (advisor)
This bachelor thesis deals with the monitoring of selected elements, mainly toxic and nutritionally important macro- and microelements, in Moravian red wines. The aim of this work was to compare the elemental composition between biovines and wines from other production systems and also to compare wines from four Moravian sub-regions. For these analyses, two analytical methods were chosen: inductively coupled plasma mass spectrometry (ICP-MS) for the determination of microelements and inductively coupled plasma optical emission spectrometry (ICP-OES) for the determination of macroelement concentrations. ANOVA (analysis of variance) test was used for further evaluation. Nickel, magnesium and potassium were identified as statistically significant elements.

Titanium, Alloys and Intermetallics for Biological and Industrial Applications
Vespalec, Vítězslav ; Jech, David (referee) ; Čelko, Ladislav (advisor)
The creation of this Bachelor´s thesis was performed as a search retrieval, which includes basic information about titanium and its alloys. In the first chapter is stated history of titanium manufacturing. Following chapter include the most important property of pure titanium, such as alotropic modifications of the crystal grid, chemical, physical and technological characteristics, there is also space, that is assigned for using contemporary division of titanium alloys, detrimental effect of impurity, shape memory effect and intermetallics instance. Third part concern about selected application in industry. The conclusion pursue about biocompatibility factor and possibility use titanium and its alloys in implantology and dental applications.

Machining of aluminum alloy component
Lačňák, Martin ; Kalivoda, Milan (referee) ; Osička, Karel (advisor)
The thesis focuses on the technology of production of the turbine-type component in Edwards company. It specifically focuses on the part of the turning production, in which in the first part an analysis of the component and the technologicity of its construction is created. Problematic aspects are analysed in terms of material structure and procedure technology. An evaluation of the former and the new supplier is made in terms of rationalization of material structure and their statistical evaluation of rationalization improvement towards keeping to geometrical tolerances. Grooving tools greatly influence the overall machining time during turning. An experiment is made to find out the measured values of the radial forces, the process of chip formation and surface roughness during grooving. The technology of procedure further deals with rationalization of the current machine OKUMA LU25-M and purchase of a new machine Mori Seiki NTX 2000, for which new tool equipment is made in cooperation with Walter company. The final technical-economical evaluation sums up all findings from the research of the given issue. In the discussion, further continuation is suggested for the research in the development and for the continuously controlled component productivity.

Optimization of Methods for Manufacturing Wormshafts
Černý, Michal ; Prokop, Jaroslav (referee) ; Kalivoda, Milan (advisor)
The subject of this diploma thesis is the optimization of the production wormshaft under specific conditions in a particular company. The optimization was requested by firm as a solution in the areas which are defined by content of this thesis. In first part, the technology of the product manufacture is evaluated. Next analysis of the original production technology is performed the regarding rationalization explained later, proposing a new form of manufacturing process. In the following parts layout variants of workplaces are assembled. These variants are based on the newly designed technology. The final part presents a control jig, which will be used in quality assurance and manufacturing workplaces and allows to measure various type of wormshaft parts. In the discussion section there is a proposal of another possible solution for manufacturing optimization these key components that make up assembly control gearbox of valves and ball valves.

Characterisation of chosen types of dairy products
Musilová, Lenka ; Buňka, František (referee) ; Vítová, Eva (advisor)
The aim of this thesis was to design technology of production soft cheese with white mold on the surface in a pilot plant conditions using unpasteurized milk that comes from grazing cows. This way I wanted to be closer to the traditional cheese manufacturing technology, over which today dominates the industrial. Final cheeses were subjected to sensory analysis in order to determine their acceptability for ordinary consumers. Sensory evaluation was carried out by two committees: students and seniors. Between the two committiees were noticeable differences, however, both commissions at the conclusion assessed the cheese as „good”. This evaluation was mainly based on lower ratings of taste (flavor) of the samples, which were quite strong and unusual for Czech consumers.
