Design of production technology of a one-handed axis and metal nut
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.

Sinumerik 840D sl. tools for programming of CNC machines
Mešina, Matej ; Kalivoda, Milan (referee) ; Polzer, Aleš (advisor)
The thesis deals with the design and production technology of the front hub for a mountain bike. The research focuses primarily on the various control systems of CNC machining apparatuses. The second chapter is devoted to the elemental differentiation of hubs, the concept of personal design of the hub, and the characteristics of the materials for its production and its verification using the FEM analysis. The third chapter deals with the design of a workpiece, instruments and the manufacturing process itself. The design of an NC program constructed in the SinuTrain 4.8. software is dealt with in the fourth chapter. The last part is devoted to the technical and economic evaluation of the proposed solution.

Design of system model of L23 Blanik sailplane
Šenkýř, Miroslav ; Mališ, Michal (referee) ; Urík, Tomáš (advisor)
The aim of this diploma thesis is to create useful reference models of the glider L-23 Super Blaník and their use for framework proposal technology of production, which will improve accuracy and reduce labor intensity of production. The introduction of the thesis describes history of glider and historical overview of geometry transmission in terms of structure. The next chapter of the thesis deals with the description of reference models and rules of their creation. Section describing coordinate systems is closely linked with the previous chapter. Another section of thesis is dedicated to the importance of reference models in the product lifecycle. The creation and tuning of reference models of glider is described in the next chapter of thesis. The penultimate chapter deals with experiment, which allowed verification of reference model and product. The conclusion of the thesis describes proposed technology of production where used verified reference models and modern tools of CAD systems refine and facilitate production. The main objective in designing of reference models was the definition of high quality and usable surfaces. Also proposal technology of production was processed in order to ensure the improvement and simplification of manufacturing process.
