Progress in technology of mold milling with coated profile tools
Doležel, Ondřej ; Bumbálek, Bohumil (referee) ; Píška, Miroslav (advisor)
This diploma thesis is involved in possible development of different types of milling molds coated with modern plows. The first part is devoted to an analysis of contemporary trends in forms production technology. The analysis includes the different types of machines and tools for making various kinds of molds and dies. Another part deals with design of dies for sheet metal shears. The thesis continues by design of the production procedure after heat treatment and finishing die by miling. For milling of die are designed miling tools, the NC program and the possible development of manufacturing the die using a new machining center and the possibility of production optimization. The penultimate point of the thesis is technical and economical evaluation of the direction of development and comparison of positives and negatoves of each method. At the final evaluation is all summed up.

Aplication of Technology Wire Electrical Discharge Machining
Slouka, Radim ; Krkavec, Martin (referee) ; Osička, Karel (advisor)
This master´s thesis focuses on the basic principles of the nonconventional technology of electrical discharge machining (EDM) with an emphasis on wire-cut electrical discharge machining performed in a mediumsized company. The thesis deals with manufacture of a belt pulley 75-8M-130, and checks of accuracy of wire-cut EDM machines. Following the study of the current status of electrical discharge machining in the engineering company, measures for assurance and increase of accuracy of wire-cut EDM machines are proposed.

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.

Production technology of parts
Bartl, Lukáš ; Kalivoda, Milan (referee) ; Osička, Karel (advisor)
The Bachelor Thesis is focused to technology suggestion and producing of bimetalic cylinder in Bernex Bimetalic s.r.o. Firstly it is focused to theoretic analyse of mechanical machining. After that, the bimetalic blank is a major issue. Some pruduction routings are suggested in this thesis and the best one is choosed. The entire report for production is prepared. A complete assessment is done on the end of the thesis in consideration of corporation capacity.
