Wire electrical discharge machining
Gvizd, Michal ; Mouralová, Kateřina (referee) ; Osička, Karel (advisor)
Bachelor thesis elaborated during the bachelor study discusses the electrical discharge cutting of materials with a wire electrode and its usage in industry. The thesis is divided into two fundamental parts –the theoretical and the experimental one. The theoretical part describes the historical development, explains the basic principle and fundamentals of this unconventional way of machining with the definition of methods using this technology. The thesis is focused on the electrical discharge machining, thus gougers are mentioned only peripherally. Afterwards, the wire electrodes used, main machine parts, cutting conditions and advantages of this technology are analyzed in detail. The experimental part deals with the evaluation of cutting surfaces of the sample components with respect to dimension accuracy, surface quality and describes factors which affect these characteristics. The emphasis is put on the machining of the tool steel. Conclusion discusses the analysis of the assembled measurements, their technological/economical analysis and outlines the direction of development in the possibilities of this unconventional technology of material separation.

Production technology for selected mold part
Mešina, Matej ; Ohnišťová, Petra (referee) ; Zemčík, Oskar (advisor)
The primary concern to be dealt with within the framework of this bachelor thesis is the concept of the variant of production technology of the mold core. The work deals marginally with the wire electrical discharge machining. Second chapter is concerned with the analysis of current production technology. Two new variants of the production technology process are introduced in third and fourth chapter. The last part of this work is dedicated to the techno-economical assessment of the proposed variants
