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.

Designing Technology for Flange Part in Two Variants
Valach, Jan ; Osička, Karel (referee) ; Kalivoda, Milan (advisor)
The aim of this bachelor thesis was to create two technological processes for component flange. For each of variants was chosen different kind of blank and different machine. In both variations, part is machined by turning. Progressive variation can produce the part for approximately one third of the time. Progressive variation of technological process is preferable since 11 pieces.
