The proposal of advanced production technology of steel molds
Opršál, Radek ; Prokop, Jaroslav (referee) ; Kalivoda, Milan (advisor)
The bachelor thesis deals with the modernization of steel mould production in the company P-D Refractories CZ a.s. The thesis focuses on the analysis of current production technology, determination of the bottleneck in production, and the analysis of the possibilities of modification of current technologies. The last part of the thesis proposes the most optimal methods of solution, introduces the technical procedure modified for the new solution and presents the evaluation of the data.

Rationalisation of electrospark machining
Janhuba, Tomáš ; Kalivoda, Milan (referee) ; Osička, Karel (advisor)
The diploma thesis deals with rationalization of EDM in the Schaeffler plant. The introductory part discuss about this type of machining, while its main purpose is the explanation of material removel process and conditions that the process must meet. It’s a summary of information that needs to be known before implementation of rationalization. The following part of the work describes an initial state of electroerosive workshop. It explains operation of the workshop or what machines are used there. In this part are also written the problems that the workshop have. After that there is part which is focused on the suggestion of solution and testing of that suggestions. The conclusions of that and whether the processess were racionalized are summarized in the technical-economic evaluation chapter and in conclusion chapter.

Nekonvenční metody obrábění materiálu
LARVA, Jaroslav
The bachelor thesis deals with the summary and characteristics of unconventional machining methods used in mechanical engineering for the agricultural or automotive industry, such as chemical, electrochemical machining, electroerosive machining, ultrasonic machining, laser machining or electro beam machining. The first part includes a systematic division and characteristics of individual methods. For each method, the history, machining principle, machining equipment, advantages and typical area of application of individual unconventional technologies in technical practice are described. The final chapter contains a comparison of individual methods depending on the achieved surface quality and dimensional tolerance.
