Machine tools for large-scale production
Nejedlý, Tomáš ; Zahálka, Jiří (referee) ; Tůma, Jiří (advisor)
The bachelor thesis focuses on the issue of processing machine in large-lot production. First part of this paper includes an overview in the field of constructional single purpose machines. Typified nodes of individual producers are described in this part. Then this part describes machines of companies which deal with the issue mentioned above. In the second part of the bachelor thesis is elaborated a project of proper production machine. The project is elaborated on the basis of facts consequent on the overview in the first part of this paper.

Assessing the influence of tool warming on the mass production process
Chrz, Jan ; Císařová, Michaela (referee) ; Lidmila, Zdeněk (advisor)
The work introduces literary study, which is devoted to sheet forming. Particularly to technologies connected with problem of pressing – blanking, bending and drawing. Further it is aimed at mass production of mouldings complicated in shape, which is nowadays supported by computer technologies (simmulation of sheet forming process, kinematics of the line, burden of the tool) and on warming of the tool. Warming of sheet formoning tools is redominatly caused by friction between the tool and semiproduct. It decreases lifetime (longevity, operable life, usable life) and quality of the moulding. Warming could not be elimitated, but could be moderated by use of lubricant for friction decrease and tool cooling, slower production or use of tempered tool.
