Laser Forming
Kameník, Jan ; Peterková, Eva (referee) ; Řiháček, Jan (advisor)
The work focuses on the use of laser beam in forming. The basic types of solid-state and gas lasers and their interaction with the material are described. It also discusses the possible mechanisms of bending in sheet metal and tubes. Subsequently, the paper discusses analytical and numerical models for determining the magnitude of the bending angle. The final part of the thesis deals with examples of laser-formed products and other possible applications in engineering.

Unconventional methods of forming
Barcuch, Jiří ; Henzl, David (referee) ; Podaný, Kamil (advisor)
Unconventional forming methods are used in the manufacture of prototypes, small series and verification of experiments. Forming technology can be used in forming by an elastic tools and by high-velocity forming. An elastic tool can be used in the form of elastomers or liquid media. High-velocity forming using detonation for shaping large parts made of hard forming materials, the principle of electrohydraulic and electromagnetic forming of metals and their alloys. Description of their principles, advantages and disadvantages when used in practice.

Pressing punches on austenitic stainless sheet
Rudolf, Bronislav ; Lidmila, Zdeněk (referee) ; Podaný, Kamil (advisor)
Thesis resolvs proposal punches in the sheet metal for heat transfer solar panels. Shapes of punches are selected – piramidal shape and lengwise shape. It is reviewed their possible production and the selected method of Guérin is described. Sheet metal from austenitic stainless 17 240 is selected for the manufacturing. Forming tool is designed with interchangeable punches and elastic medium for various modifications and comparing shapes of punches. It is used hydraulic press CZR 600 for a experimental production.
