Technological Design of Part "impeller"
Kotrsal, Miloš ; Kubík, Roman (referee) ; Kalivoda, Milan (advisor)
This work is analysing existing technologies of paddle wheel production in a concrete engineering company which is engaged in turbochargers production. It is a breakdown analysis of technology from semi-finished product production to technological process of parts production, processing machines and tools. Here is proposed a new process of production technology. In the conlusion there is shown technical-economical comparison of existing and new technology.

Proposal production of a chain wheel with the unconventional methods of machining use
Mikeš, David ; Kubík, Roman (referee) ; Dvořák, Jaromír (advisor)
This bachelor thesis deals with the application of unconventional methods in machining (use of laser and hydro-abrasive beam) during chain wheel production. Firstly, the unconventional methods are divided according to the overwhelming effect of material separation, and then these methods are briefly described. In the second part of the thesis, you can find the technological process of chain wheel production with the usage of cutting operation method, which is followed by the assessment of production costs. Afterwards, the chain wheel is produced with the application of laser and hydro-abrasive beam. The final part of the thesis contains comparison between the unconventional methods and the conventional method of cutting operation. The comparison is based on the achieved structure of surface of the gear tooth, the production time and the economic point of view.

Custom-made production upon a vertical CNC machine
Okáč, Petr ; Kubík, Roman (referee) ; Kalivoda, Milan (advisor)
The thesis focuses on the topic of custom metalworking, which is familiar to author due to his experience in the field. The first part describes advantages and disadvantages associated with business of small and middle companies, their role in economy and everyday problems they need to solve. The second part compares the manufacturing of a steel part on CNC machine to manufacturing it using conventional machines and evaluating possibilities for custom manufacturing.
