Manufacture of massive castings and their defects
Doležal, Petr ; Martínek, Ludvík (referee) ; Záděra, Antonín (advisor)
Object of this master’s thesis is accomplished analyze the range of foundry of steel ŽĎAS a.s., Zdar nad Sazavou and make the type massive steel castings and analysis of existing technology foundry and metallurgical defect. The beginning of this master’s thesis is dedicated to the manufacturing of steel foundries range ŽĎAS a.s., Zdar nad Sazavou. The following section is devoted to manufacturing technologies for the production of massive steel castings. In the final part of this thesis are described metallurgical and foundry defects of the typical castings of steel foundry and proposals to eliminate these undesirable defects. End thesis includes a summary of the results and trends in the development of research in the production of massive steel casting.

Trend of exercise electrodischarge machining
Jakeš, Jan ; Kalivoda, Milan (referee) ; Osička, Karel (advisor)
In this work, description of a basic principle of electro discharge machining and its technological possibilities was made. Possibilities of individual EDM machine producers and their comparison were described. Furthermore, the use of electro discharge machining in Zdas a.s. was shown. Trends in a development of the electro discharge technology are included, too.

Modernizing of machinery
Martínek, Lukáš ; Prokop, Jaroslav (referee) ; Osička, Karel (advisor)
This work is focused on modernizing stock of machinery problem in roughing big parts in Žďas a.s. The aim is to analysis contemporary condition of roughing big parts, define area of possible savings, suggestion modernizing stock of machinery of this company and on its end technoeconomic evaluation each of that variant and recommendation of final solution.
