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.

Manufacturing of Gearwheels Using Various Technologies
Řezáč, Matěj ; Prokop, Jaroslav (referee) ; Kalivoda, Milan (advisor)
The present bachelor thesis is focused on the production of spur gears. The theoretical part summarizes the information related to toothing, its production and inspection. In the practical part, three technologies of spur gear manufacture are selected the gears are made. Finally the thesis compares the spur gears produced by these technologies geometrically and dimensionally

Water Jet 2009. Proceedings
Sitek, Libor
Conference Water Jet 2009 - Research, Development, Application, which is organized by the Department of material disintegration of the Institute of Geonics of the ASCR, v. v. i., is the first meeting of producers, users, designers and other people interested in technology of high speed water jet in the Czech Republic. The main objective of the conference is to provide forum for exchange of knowledge, information and experiences in areas of research, development and application of water jet. Although the conference was originally intended as a more or less local meeting of experts from the Czech Republic, a number of foreign participants proves that this issue is very attractive far beyond the borders of the CR. Problems solved in contributions are very diverse: they range from basic research through traditional and less traditional application of technology in practice to reflection on the impact of the current economic crisis on job shops.

Turning by high-speed abrasive water jet – our experiences
Sitek, Libor
The paper describes and analyses our own experiences concerning technology of turning by high speed abrasive water jet. Technology development as well as present stay-of–the-art in given area are introduced in brief. Possibilities of application of such machining method especially for shaping and preparation of testing rock specimens suitable for determination of physical-mechanical properties of rocks are also discussed.
