Technology of wire electrical discharge machining
Galko, Adam ; Mouralová, Kateřina (referee) ; Osička, Karel (advisor)
This thesis talk about practical application of wire electrical discharge machining (WEDM), which belongs to electro-erosion machining methods. This thesis is focused on the production of cutting dies produced by company FOR MIX s.r.o. Trenčín. We can consider the cutting die as a typical product of company´s product program. In the practical part of this diploma thesis, there is detail of technological aspects and operating costs for wire electrical discharge machining technology in specific condition of company FOR MIX s.r.o.

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

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.

Electroerosion machining of materials used in the aerospace industry
Zubáková, Alexandra ; Mouralová, Kateřina (referee) ; Kalivoda, Milan (advisor)
This diploma thesis deals with the issue of electroerosion machining of materials used in the aerospace industry. The introductory part presents the layout of aerospace materials and the methods by which they can be machined. The next chapter describes the basic principles of EDM. The experimental part is focused on electroerosive cutting of NIMONIC 263 alloy. The greatest emphasis was placed on determining the influence of the cutting wire material on the rate of contamination of the surface layer of the workpiece. The quality of the machined surface was assessed depending on the used wire and the selected machining parameters.

Technology of wire electrical discharge machining
Brázda, Radim ; Krkavec, Martin (referee) ; Osička, Karel (advisor)
This master´s thesis deals with unconventional technology of wire electrical discharge machining. There are described the principles and essence of electrical discharge machining and the principles related to wire electrical discharge machining with emphasis on the application of this technology in terms of medium-sized engineering company. There is also described the complete assembly of technolgy wire cutting and machining on wire cutter Excetek V 650. Then in the work there are statistically evaluated parameters precision machined surfaces, specifically to the belt pulley 116-8M-130. At the end of the work there is the technical-economic evaluation that addresses the hourly cost of machining on wire cutter Excetek V 650.
