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.

Methods of printed circuit board design
Cirkovský, Jaroslav ; Vrba, Kamil (referee) ; Herencsár, Norbert (advisor)
The main purpose of my bachelor thesis was to acquaint with issues of printed circuit boards and to create multimedia videos. The first part deals with questions of the accuracy, miniaturization and applied cases with different outlets. Following chapters dissert on electromagnetic compatibility from the view of basic rules, which have to be observed in order to reach the best functionality of the printed circuit board. There are also other issues - components increasing the reliability of printed circuit board and the comparing of methods of printed circuit board design. The final part of my bachelor thesis discusses outputs which are necessary in practice. This includes technical and design documentation and the technology of production the printed circuit. The last chapter describes created multimedia utilities which help us with printed circuit boards design via the program Eagle.

Solution technology of adjustable V-belt pulley
Láznička, Pavel ; Fiala, Zdeněk (referee) ; Kalivoda, Milan (advisor)
At the beginning, the thesis contains description of belt drives and balancing of an adjustable belt pulley. The topic of the next chapter is concerned with the evaluation of technological aspects of unit and series production. It is followed by a choice of material, a semi-finished product and a calculation of material consumption. A technological procedure with selection of machine tools and selection of suitable method of production with calculations of a producing time are described afterwards. At the end, the ecological aspects are assessed. The conclusion comprises technological and economic evaluation of production.

Technology Solution for Components: a Valve with Condensing Loop
Jarkovský, Marcel ; Kubík, Roman (referee) ; Kalivoda, Milan (advisor)
This Master's thesis focuses on technology of production of the valve body produced by company Armaturka Vranová Lhota, a.s. First part introduces the company and their range of products. Second part of the Dissertation focuses on analysis of the part with details on construction, material and choice of three options of semi-finished product based on minimum expenses. In the third part are introduced current technological processes of assembling, weldment and valve body production. There are proposed two new production options to the current technological production process of body valve using different tools and jigs. New production instructions are calculated to establish times of production. In the conclusion of dissertation is the choice of optimal option considering habitual practice and conditions of company. For this chosen option is calculated technical-economic evaluation.
