Laser cutting
Baran, Marek ; Mrňa, Libor (referee) ; Kubíček, Jaroslav (advisor)
The thesis elaborates cutting of thick sheet metal using the laser technology. Beside technological aspects of laser cutting, the project also deals with utilising laser technologies in practice and compares laser cutting to other ways of cutting sheet metal. The experimental part, which was realized in STEELTEC CZ, was concerned with optimization of focal point for cutting 20 mm sheet metal of S235JR. The samples which were cut on a CO2 laser were compared to samples made by plasma and water cutting machines. The researched parameters were roughness, shape, time and price.

Possibilities of stencils production by a laser on the device AUREL 300
Doležel, Tomáš ; Šandera, Josef (referee) ; Adámek, Martin (advisor)
This bachelor’s thesis deals with the possibilities of production of rework stencils using a trimming laser AUREL 300. The first part focuses on the basic description of the thick-film technology and the possibility of using lasers in this area. The most common methods of producing stencils for printing solder pastes are described in the next section. Machining of various non-traditional materials and the actual design, realization and testing of rework stencils for printing solder paste of these materials is documented in the practical part. Furthermore, options and recommendations for the production of rework stencils are given in this thesis.

Unconventional production technology of chains
Hostinský, Michal ; Mrňa, Libor (referee) ; Osička, Karel (advisor)
Unconventional technologies and their continual development brings along new possibilities in the manufacturing process. The submitted project is focused on solving problems in the procession of sheet metals in the manufacture of special parts of roller and conveyor chains. In the assessment of the technology of components, laser cutting was evaluated as the most optimal technology. With this goal, there was a public tender in terms of the purchase of a new machine designed for the manufacturing operations of the company of RETEZY Vamberk. This company ranks among the most major manufacturers of conveyor, roller and special chains in Europe.

Unconventional Technology of Laser Cutting
Indra, Jaroslav ; Kalivoda, Milan (referee) ; Osička, Karel (advisor)
The thesis deals with the technology of laser cutting. The beginning is concerned with a general description of laser technology and laser division into basic groups. Next part refers to possible industrial use of laser beam, especially for cutting. Other chapters deal with the components suitable for the manufacture of this technology, technical preparation of production and the proposal to increase manufacturing flexibility when changing products. The last part is devoted to technical and economic evaluation.

Manufacturing possibilities of motorcycle brake wheel
Rozum, Josef ; Dohnal, Ivo (referee) ; Podaný, Kamil (advisor)
This bachelor thesis presents a variant solution of mass production of motorcycle brake wheel. These are part of rotating component of large diameter and small thickness made up mainly of carbon steel. The thesis presents methods for the production of unconventional machining technologies and methods of molding. As appropriate variants were selected technologies of laser cutting, water jet cutting, plasma cutting, blanking and fineblanking. The individual methods are described and evaluated their suitability for production. For fineblanking method which seems to be optimal is indicated the production process.

Technology of Production Parts solar Panels
Midrla, Zdeněk ; Sedlák, Josef (referee) ; Osička, Karel (advisor)
This work is focused on a proposal of technological production process of components of a solar panel. The proposal of technological production process is suggested in terms production series of 9000 of pieces per year. The work also contains an analysis of construction of all components of the air separator equipment. There are suggested variants of stocks for some of the components. It also includes a selection of the most favourable variant in terms of material usability and practical aspect as well. There is an technological production process designed by the chosen varinat including of a production instructions.
