The pilot project of rotary component production
Toman, Lukáš ; Prokop, Jaroslav (referee) ; Osička, Karel (advisor)
At the begining of the bachelor thesis is a theoretical part that deals with the basic principle of machining. Cutter arbor 40 × 27 ČSN 24 1440 is assessed from technological point of view. Yearly production of the arbor is 17 000 pieces. The main theme is a technological evaluation of the production process from two type sof semi finished product, circular bar hot rolled and forging both made of 14 220.0. For the technological process are chosen machina and tools. Production instruction is elaborated for rough turning operation and the reset is machining time. In the conclusion is chosen semi finished forging according to the technological and economical evaluation of the production process.

Rationalizaton technology of production solid 14.037.270
Lačňák, Martin ; Osička, Karel (referee) ; Prokop, Jaroslav (advisor)
This thesis deals with the rationalization of the existing body of machining 14,037,270 for five-axis CNC machine HERMLE C20U with Heidenhain control program. The work is focused mainly on streamlining the production of holes in the part. In the introduction technology is developed, which was created by Elakov. Based on analysis of existing housing production technology, new tools have been selected and designed a new technology. By consolidating all of the results efficient and economical production alternative was designed.

Cutting materials of sintered Carbides end their heat Resistance
Doležalová, Petra ; Bumbálek, Bohumil (referee) ; Osička, Karel (advisor)
One of the fundamental properties of cemented carbides is their resistance to forming and spreading cracks under the thermal stress. The bachelor’s thesis is focused on description of known technological methods that are used for testing of thermal fatigue of materials made by cemented carbides. Part of the bachelor’s thesis is also the description of the thermal fatigue, characterization of the appearance and orientation of cracks that occur in cemented carbides, according to the distribution of the thermal field. Last but not least, the bachelor’s thesis contains the information concerning the problematic of cemented carbides and about their constituents, technology of production and their application.
