Modern methods in spur gearing production.
Kopečný, Libor ; Zemčík, Oskar (referee) ; Zemčík, Oskar (advisor)
The division and comparison of modern methods of production of spur gearings. The introduction is focused on the characteristics and description of cog wheels. Furthermore, the types of gearing and gear mechanisms are introduced. The main part of the text deals with individual ways of a production of spur gearings including finishing methods. The following part of this work describes the importance and possibilities of heat and chemical-heat gearing production. In the last chapters, the evaluation and achieved results of individual technologies of gearing production are introduced.

Roller burnishing tools in engineering.
Henzl, David ; Zemčík, Oskar (referee) ; Zemčík, Oskar (advisor)
This bachelor work deals with chipless technology of roller burnishing and tools with bearing on roller burnishing of circular orifices and back-to back surfaces. In the first part of the work elementary conections concerned with finishing and hardening of machine components by roller burnishing are explained. In the next part the classification of tools produced by German company Baublies AG is realised. In the following part there are examples of roller burnishing method utilization in the machine industry. Hereafter, the technical – economical evaluation and comparation with conventional methods of finishing such as lapping, honing, superfinishing, polishing, grinding, core – drilling and reaming, boring work, diamond burnishing and shot peening is realised. In the conclusion of the work the assumptions for the future are given.
