Application of modern technologies for the production of spare parts airsoft guns
Král, Ondřej ; Zemčík, Oskar (referee) ; Jaroš, Aleš (advisor)
This bachelor thesis describes design and manufacture of airsoft spare parts. Selected spare parts were hammer and spring holder, which were designed in 3D parametric software Autodesk Inventor 2016. Chosen method to manufacture spare parts, was Fused Modeling Deposition, which is part of Rapid Prototyping technology. The device for producing parts was 3D printer uPrint. The manufacture of silicon mould was based on printed spring holder, which was used for parts manufacture, by casting plastic materiál. Thesis is completed with a technical-economical evaluation, in which it was found that the silicon mould casting is more profitable in the production of more parts.

Improvement of manufacturing technology of flange
Dvořák, Jakub ; Fiala, Zdeněk (referee) ; Jaroš, Aleš (advisor)
This diploma thesis focuses on improvement of the existing technology of the flange part in cooperation with the company Znojemské strojírny, s r.o. The theoretical part describes the technologies used in machining of the component. Subsequently, cutting materials and aluminum alloys are dealt with. A detailed analysis of the existing technology is performed in the practical part of the thesis followed by rationalization of the production process, which was carried out with respect to time and financial savings. A new technological procedure is developed after the improvement of the current production process. Finally, a technical-economic evaluation of the design improvement process is carried out.

Machining on a universal milling machine equipped with a divider
Luňáčková, Nikola ; Jaroš, Aleš (referee) ; Kalivoda, Milan (advisor)
This bachelor's thesis deals with milling using a dividing device. The aim is to acquaint with the technology of machine milling, its kinematics, machines, tools and about the use of a dividing device. The theoretical part deals with machine milling on a universal milling machine equipped with a cutting device and milling using CNC machines. The practical part compares these two types of milling using a product made on a CNC milling machine and a machine universal milling machine equipped with a cutting device, using the same tool diameters.

Silicone molds and their use
Rudolf, Jiří ; Zouhar, Jan (referee) ; Jaroš, Aleš (advisor)
Bachelor thesis is focused on the design and production of a headphone holder. Thesis is divided into theorethical and practical part. The theoretical part is described Rapid Prototyping technology, precision casting with use of silicone molds and precision investment casting. The practical part is focused on the design of a headphone holder in CAD system Autodesk Inventor and following production via two different methods. The first way is 3D printing by Fused Deposition Modeling method and the second way is casting wax and plastic models using a silicone rubber mold. Conclusion of this thesis contains technical-economic evaluation and comparison of both manufacturing methods.
