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.

Tools for the Punching Process
Jelínek, Daniel ; Šrajer, Jan (referee) ; Peterková, Eva (advisor)
Elaborated project is focused on the study of die cutting/punching technology and its aim is research and comparison of machines and principles used, given to the processed material. Within the project, differences between two types of tools used are compared, namely for die cutting of cardboard sheets and punching of metal sheets. The project also includes a design of die cutting tool for pharmaceutical folding boxes with complete stripping tool and counter plate on automated die cutting press Bobst SPanthera 106 LE.

The analisys of possibility laser cutting
Plevka, Vojtěch ; Kalivoda, Milan (referee) ; Osička, Karel (advisor)
Master’s thesis deals with application of lasers in manufacturing, mainly with the technology of cutting material. This technology is compared with the technology of punching and cutting sheet metal, with the aid of control specimens. The parameters of surface structure, dimension accuracy and appearance of cut-ting surfaces are compared. By consensus of results the recommendation for practical realization was created.

The manufacturing of coating metal sheet part
Sykáček, Jiří ; Hušek, Martin (referee) ; Císařová, Michaela (advisor)
SYKÁČEK Jiří: Production of a sheet metal part with a surface finish This project, elaborated as a part of my B2307 bachelor studies, has been compiled on the basis of a customer requirement to produce a battery cover exposed to an increased corrosion risk. It deals with the production technology of the part using various sheet metal materials of different surface finish. The most suitable solution has been found in using a cutting and a bending press. The chosen production method has been evaluated with regard to technological difficulties connected to processing thus modified sheet metal as well as with regard to economical cost of the production. Forming processes have been executed using a TRUMPF TC200R cutting press, having a nominal shearing force of 165 kN, and URSVIKEN Optiflex bending press, having a nominal pressing force of 1300 kN. Forming tools are optimally chosen according to the parameters of individual types of sheet metal. At the end the project evaluated the most convenient material to produce this part.
