The Use of a Waterjet Technique in Finishing Operations
Jantač, Marek ; Osička, Karel (referee) ; Kalivoda, Milan (advisor)
The bachelor thesis deals with abrasive waterjet cutting. In the first part we dis-cuss the possibility of using an abrasive jet in various industries, its advantages and disadvantages. Furthermore, abrasive jet machining methods such as cutting, turning and milling. Then focuses on the technology at AWAC company, which were cut off samples for subsequent measurement. The aim of the measurements was to determine and compare the surface roughness of the samples were cut at different parameters.

3D abrasive water jet
Maříková, Petra ; Prokop, Jaroslav (referee) ; Osička, Karel (advisor)
This master's thesis deals with abrasive water jet cutting in the introduction. Another part is focused on deploying technology 3D cutting with abrasive water jet in conditions of a medium-sized company. This technology allows the elimination of bevels, and angel cutting. The following sections deal with technological capabilities of the specific machine and experimental comparison of samples cut by AWJ and DWJ technology. The work also includes a sample layout of machines on existing premises, the proposal for a potential component base and economic evaluation.

Cutting of Water Jet
Zouhar, Ondřej ; Slaný, Martin (referee) ; Osička, Karel (advisor)
The work developed in the master's program, describes the technology of water jet cutting. The theoretical part deals with the description of this technology and it explains the basic concepts used in this field. The practical part was designed to verify some theoretical knowledge. Therefore, several experiments were performed, while there was studied the influence of abrasives on the final quality of the surface and the level of the generated noise. The practical part was completed by the production of the selected component and its technical and economic evaluation.

The unconventional Method of Cutting Water Jet
Prax, Ondřej ; Slaný, Martin (referee) ; Osička, Karel (advisor)
The master thesis contains a literature search dealing with the unconventional technology of water jet cutting. The first part is aimed to description of the water jet technology and shows the possibilities of controlling and awarding data for cutting. Follows the chapter about the influences of the input parameters to a surface quality and machining accuracy. The thesis also giving an account of ecological factors of the water jet cutting. The description of the whole technology for production of the sprocket is a part of the thesis. The last part of the thesis is solving the economics of the water jet cutting technology, especially for production of the sprocket with comparing dependency of the cutting conditions.
