(Žilinská univerzita v Žiline, 2023) Melo, Borislav; Dostál, Robert
Cutting technology is one of the basic and supporting methods, preferably of dividing materials. The preparation of material for further processing cannot be imagined without the use of cutting technology. The text of the contribution describes the geometric solution of the cutter and also the construction of the used tool for the area of trimming sheet metal and creating qualitatively more suitable cutting surfaces. The goal of the contribution was the design of a tool for the application of sheet metal trimming.

The contribution presents the analysis and issues of glass forming in a forming tool with external heating. The necessary theoretical knowledge and properties of glass, which are necessary for solving the design of the forming tool, are listed. technological methods of glass forming are mainly press-blowing and forming with a double-blowing system. With the help of the described tool, glass can be relatively successfully shaped, which is inserted into the tool in the shape of a plate. The glass plate, which is bent into a cylindrical or hemispherical shape, is placed on the press and heated with a flame until the glass is sufficiently soft to work with.
