Machining of hard materials
Pech, Ondřej ; Kalivoda, Milan (referee) ; Osička, Karel (advisor)
The objective of this paper is to analyse the issue of machining of hard materials on Swiss-type automatic lathes at Decoleta, a.s. In the form of research, analyses are being done of the materials used, possibilities of the available cutting tools and suitable tooling materials. The current technology used in the production of two different stainless steel elements is further being analysed in detail, including the subsequent suggestion of rationalisation actions. These actions include, mainly, the design of new tools from CBN for both elements, which shall replace the current tools made of sintered carbide, but also reworking of production technology for the Pin on another more suitable type of machine, including a new CNC program and complete drawings.

Machining of aluminum alloys
Pavliš, Jan ; Kalivoda, Milan (referee) ; Osička, Karel (advisor)
Bachelor thesis is focused on manufacturing of component YZ-RIGEL in Frentech Aerospace s.r.o. factory. The component is destined for the aerospace industry, specifically for the Airbus A350. The theoretical part of the thesis analyzes the base of aluminum alloys as well as the machinery park of the company. The CNC centers MCFV 1060 and PICOMAX® 95, on which the part is manufactured, are discussed in more detail too. The practical part deals with creation of production process including toolbars. The end of the thesis is devoted to calculation of machine time needed for the component production.

The analisys of possibility laser cutting
Plevka, Vojtěch ; Kalivoda, Milan (referee) ; Osička, Karel (advisor)
Master’s thesis deals with application of lasers in manufacturing, mainly with the technology of cutting material. This technology is compared with the technology of punching and cutting sheet metal, with the aid of control specimens. The parameters of surface structure, dimension accuracy and appearance of cut-ting surfaces are compared. By consensus of results the recommendation for practical realization was created.

Verification Tightness of Headlamp
Maule, Jiří ; Pernikář, Jiří (referee) ; Osička, Karel (advisor)
The task of my work is to describe and analyse tightness control of front headlights in automotive industry. This work is concerned with theoretical indi-cative allocation according to the light source, development and contruction of headlights in preamble. There is shown the way of disclosing the outflow pres-sure area at loose headlight in next part of this work. It defines the most proba-bly caused reason of untightness with help of Ishikawov diagram. There is also made evaluation of measured values and determined the main cause of un-tightness. At the end there are shown possibilities of statistic´s evaluation of measured values and made changes necesarry for untightness elimination.
