MODERN TECHNOLOGIES IN WIRE ELECTRICAL DISCHARGE MACHINING THE METAL ALLOYS
Mouralová, Kateřina ; Karpíšek, Zdeněk (referee) ; Pokorný, Peter (referee) ; Píška, Miroslav (advisor)
The dissertation is focused on streamlining production on wire electric discharge machine during cutting metal alloys, specifically low-alloy steel quality by CSN 41 4220. The first part contains a study of the current and modern technologies EDM wire cutting. The second part is focused on identifying key parameters to influence the WEDM process, a detailed analysis of the machined surfaces of samples and wire electrodes used for cutting. The result of this work was to explore the possibility, whether by performing planned experiment and subsequent evaluation in the future to determine exactly setting the key parameters influencing the process of WEDM.

Design of production technology of shaped cover
Doležal, Václav ; Štroner, Marek (referee) ; Dvořák, Milan (advisor)
This thesis presents a design technology of forming a shaped lid focused on cutting, bending, drawing, as well as trimming and making the required holes. There is described several basic variants of sheet metal forming based on the literature. Production of holes of specified cover, for an annual production of 100 pieces of shaped lid, is solved by unconventional technologies. From subsequent economic evaluation of selected technologies is chosen an appropriate technology to minimize production costs.

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.
