Technology project and layout for holder
Mottl, Jan ; Žák, Ladislav (referee) ; Rumíšek, Pavel (advisor)
Technology project and layout for holder. Bachelors thesis of the bachelor’s studies the 3rd year. School year 2008/2009, education group 3P1. FSI VUT in Brno. Institute of technology, department of forming. April 2009, pages 47, pictures 28, tables 2, supplements 9. Bachelors thesis which was elaborated in the frame of the bachelor’s studies branch 2307 submitting the technology project and layout of the holder. Component are produced from material 11 321 using of undermentioned literature pursuit a problem of the select material, sheet metal cutting and bending which was designed by cutting with processual tool and bending tool. At designed cutter and bending was used of standardised components. Project organization of production is designed so, to keep up produce of requisite series in a year.

Technology project and layout for holder
Perutka, Michal ; Žák, Ladislav (referee) ; Rumíšek, Pavel (advisor)
PERUTKA, Michal. The draft layout of technology and production of holder. Thesis of the Bachelor´s studies, 3rd year, academic year 2008/2009, education group 3P1. FSI VUT Brno, Department of Engineering Technology, Department of Forming, May 2009, pages 50, pictures 23, tables 8, supplements 9. The project solved in the framework of Bachelor´s studies presents a proposal of the technology and production arrangement of a holder – piece of steel 11 320.0. The estimated series production is 1 000 000 pieces ar year. The thesis describes the manufacturing operations sheet metal cutting, bending and surface treatment. Processual cutting tool used standardized parts and should be treated as a simple assembly clamped to the press LENR 40-A (manufacturer ŠMERAL Trnava, Slovakia with a nominal shearing force 400 kN), which is also used for the bending operation realized on a simple bending tool, clamped also in the form of a stand in the same kind of press.

Material models for simulation of dynamic forming operations
Fiala, Zdeněk ; Forejt, Milan (referee) ; Šlais, Miroslav (advisor)
The work deals with basic information about material models for simulation of dynamic forming processes. It describes software based on the finite element method and its use for simulation of dynamical forming processes. Next it presents basic theories about mechanical behaviour of materials under dynamical loading conditions and thein evaluation. It compares constitutive equations which describe materiál behaviour depended ontemperature and strain rate.

Optimalization of Temperature for Semi-hot Forming of Roll Bearings
Hrouzková, Andrea ; Klakurková, Lenka (referee) ; Doležal, Pavel (advisor)
This bachelor's thesis solve the problems about optimalization of temperature for semi-hot forming of roll bearings steels. The purpose of this thesis is finding the optimal interval of temperatures, in which 100CrMnSi6-4 bearing steel shows good strain and deformation characteristics after forming. Methods for data evaluation of mechanical properties are the tensile and upsetting tests which were performed on higher temperatures. It was microscoped microstructure changes of the bearing steel 100CrMnSi6-4 during temperature influence and classification with the light microscope.
