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.

Analysis of defects of copper alloy after wire electrical discharge machining
Vontor, Jakub ; Osička, Karel (referee) ; Mouralová, Kateřina (advisor)
Electrical discharge wire machining, which represents non-conventional machining technology is up on very high technological level. However, due to this type of machining many of defects are set on the material and the quality of machined surface is changed according to set parameters of machine. Complex study was created with the aim of optimization these parameters according to final quality of surface and right wire speed. This study include experiment with 33 samples, every of these samples was machined with different parameters, results of these machining were analyzed.

Analysis and use of wire cutting technology
Patočka, Josef ; Osička, Karel (referee) ; Kalivoda, Milan (advisor)
The diploma thesis focuses on the topic of electroerosive machining with greater emphasis on wire cutting technique. The first part clearly describes the principle of electroerosive discharge and its subsequent effects that cause material removal in the given working conditions. This includes the individual methods of electroerosion and the individual accessories that aid the process. The second part is a theoretical analysis of the cutting process using a wire electrode. It describes the machining method, machining strategy and a complete overview of the accessories that accompany the cutting process. The third part of the thesis includes a practical demonstration of the production of a typical representative for wire cutting and then there is evaluation from an economic point of view. Furthermore, there is clear analysis of the surface quality and the final evaluation of the condition of the component.
