Wire electrical discharge machining at production of tools for working of wood
Sedláček, Jiří ; Prokop, Jaroslav (referee) ; Osička, Karel (advisor)
My thesis is aimed at the application of wire electical discharge machining technology in the production of woodworking tools. All of this in the conditions of Vydona company. There is a theory of machining method plus a well-aranged division of cutter tools for wood in the introduction. The practical part describes in detail the procedur of cutting shaped plate out of tungsten carbide. As a result of the technical and at the same time the economic evaluation is an establishment of hourly rate for machine.

Utilization of electrodischarge machining technology
Dlabaja, Zdeněk ; Mouralová, Kateřina (referee) ; Osička, Karel (advisor)
Electrical discharge machining (EDM) is quite simple but very effective method for machining of materials. This method has an irreplaceable place in modern engineering. The technology of the EDM is theoretically described in this work. The aim of this work was to judge the advantages and disadvantages of this technology, and its application in a tool company Brenas, Ltd. A component typical for production using EDM was chosen for this judgement. The shape complicatedness and necessary dimensional and surface quality can be clearly seen in this component.

Analysis of electro-spark cutting and digging machines from firm name Emotek s.r.o. and their enforcement on EU market
Svoboda, Jiří ; Zemčík, Oskar (referee) ; Zemčík, Oskar (advisor)
The aim of this work is to make the reader closer to the principle and usage of an uconventional technology of shaping metal materials - electro discharge machining. The first part of the work contents historical dates, an explanation of the principle and the technological insertion. In the second part I concentrate on the range of products of the Slovakian company Emotek, to be specific, on their spark cutting machine EIR 005. I sample the description of the machine and its technical - economic comparison with the competitive electro - spark machines. The whole work is primarily concentrated on the electro - spark cutting machines. The digging machines are mentioned only marginally. Lastly, the work should persuade the readers of indisputable advantages of this technology and its utilization. Furthemore to introduce Emotek as a company competing with other external producers as well as with merchants and to point out the further possible progress of the company and its activity in the electro - discharge machining branch.
