Production technology for a vacuum pump component
Horák, Adam ; Kalivoda, Milan (referee) ; Zemčík, Oskar (advisor)
The bachelor's thesis focuses on the design of a new or alternative technology for the component of the orbital scroll wheel 10i for the vacuum pump nXDS10i. The component is made of an aluminum alloy. The aim is to transition to a higher level of automation compared to the original technology, with the implementation of High-Speed Cutting (HSC) machining. The thesis includes an introduction and analysis of the component, including information about the alloy used, an analysis of the original technology, and its variants for optimization. This is followed by the proposal of a new technology and automation design, meeting the conditions set by the manufacturer of the component. The proposal of the new technology includes the design of a new technological process and clamping method. The thesis also includes a technical and economic evaluation of the original technology, the optimized original technology, and the new technology.

Manufacturing processes of components with a minimum number of tools
Zábojník, Zdeněk ; Drbal, Martin (referee) ; Kalivoda, Milan (advisor)
The bachelor thesis focuses on manufacturing components with a minimal number of tools on a CNC lathe. To demonstrate the production of components with a minimal number of tools, manufacturing procedures for two components, A and B, were designed. Component A is a typical component of simple shape that can be manufactured with a low number of tools. Component B is more complex in shape, and two production variants were proposed for it: one with a higher number of tools and one with a reduced number of tools. For both components were were selected tools, proposed manufacturing procedures and time calculations were carried out. In conclusion, a technical – economic evaluation and comparison of both variants for component B were conducted.

Measuring cycles in control systems of CNC machines
Hamřík, Jiří ; Jaroš, Aleš (referee) ; Gregor, Lukáš (advisor)
In the first two points, the bachelor's thesis focuses on the comparison of CNC and NC machines and methods of control and programming of CNC machines, a description of the control system of CNC machines from selected producers and the characteristics of measuring cycles. Two producers were selected to describe the technology of measuring tools and workpieces using probes. In the third point of the bachelor's thesis, a practical demonstration of measurements with tool and workpiece probes from RENISHAW is performed. A tool correction was performed followed by measurement of the workpiece with a probe. For statistical evaluation, digital micrometer measurements were added, including comparison and evaluation of the obtained results.

Design of an engraving LED laser
Kasík, Martin ; Sliwková, Petra (referee) ; Dvořáková, Jana (advisor)
This thesis is focused on the search of unconventional machining methods, especially on the technology of laser beam machining. It deals with the area of laser cutting and engraving and examines the influence of individual technological parameters on the given process. Furthermore, there is proposal of design of hobby LED engraving machine, its supporting structure, HW and other electronic components. The prototype of the device is physically assembled and its functionality is verified in the form of several engraving tests of raster and vector formats of graphic materials, and some several shape cuts are made also. The technical evaluation of the assembled equipment, evaluation of tests performed and cost calculation is part of the work too.
