Straightening technology of semi-finished products
Sikora, Marek ; Řiháček, Jan (referee) ; Peterková, Eva (advisor)
The main aim of this thesis is to create a general overview of processes that are applied in straightening semi-finished products. These processes include manual methods as well as mechanical ones. This work also informs about advantages and disadvantages of these processes based on published researches. This paper is supposed to give a basic overview of categories of machines and tools that are used in certain straightening technologies.

Computational analysis of leveling of square cross section rods
Šebek, František ; Návrat, Tomáš (referee) ; Petruška, Jindřich (advisor)
Current requirements in mechanical engineering require more accurate operations and more efficient technologies. The aim of this thesis is the analysis of the leveling of square rods. The main problem is the setting of the leveling machine for the specified material and geometric data so that the initially curved material, which passes through alternatively positioned offset rollers, is leveled as much as possible. The main factor in the leveling process is the plastification of the material used for the redistribution of the residual stress. Based on existing theo-retical knowledge in this field, programs are set up to simulate the passing of the rod through the leveling machine. Further, modifications leading to the improvement of the whole process are presented. Finally, there is a verification of the results which is made independently of the submitted solution and processed by the finite element method.
