Abrasive water jet cutting
Midrla, Zdeněk ; Kubík, Roman (referee) ; Osička, Karel (advisor)
This master thesis is consisted of literature search and practise part with focusing on the theme of abrasive water jet cutting. Introductory chapters deal with various methods and principles water jet cutting. Following chapters deal with quality of cutting surface by abrasive water jet cutting. After these chapters is introduced machine equipment of water jet cutting technology. At the end of this theoretical part are listed advantages and comparison with other unconventional technologies. In the practical part is solved design of machinery with regard to manufacturing technology of component flange in series 630 000 pieces per year. Last chapter describes economic evaluation of production.

Water Jet Cutting
Odehnal, Ondřej ; Fic, Miloslav (referee) ; Kárník, Jan (advisor)
The following bachelor’s thesis deals with an unconventional technology of waterjet cutting. Content of the thesis is focused on the description of the technology, basic classification and description of utilization methods. Machinery used in this technology is described below. At the beginning, this work introduces the history and describes the principle of the water jet. Following is the classification of the methods used for water jet. The most important components of devices operating with this technology are described in the next section. The last part is the description and evaluation of an experimental verification of theoretical knowledge. The quality of cut and the behavior of the water jet was examined for different cutting parameters on cutting samples. Evaluation of the thesis is included in the conclusion.

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 force of water jet on a flat surface
Kasal, Milan ; Soukup, Lubomír (referee) ; Fic, Miloslav (advisor)
This bachelor thesis discusses about the theory of fluid mechanics. In the first part of work are listed the basic hydrodynamic laws for ideal and real fluid. Further there was derived force acting on the surface. The second part is devoted to the practical use of force water jet to generate electricity and cutting of material. The objective of the last section, was practical verification of derived relations during laboratory measurements.

Manufacturing possibilities of motorcycle brake wheel
Rozum, Josef ; Dohnal, Ivo (referee) ; Podaný, Kamil (advisor)
This bachelor thesis presents a variant solution of mass production of motorcycle brake wheel. These are part of rotating component of large diameter and small thickness made up mainly of carbon steel. The thesis presents methods for the production of unconventional machining technologies and methods of molding. As appropriate variants were selected technologies of laser cutting, water jet cutting, plasma cutting, blanking and fineblanking. The individual methods are described and evaluated their suitability for production. For fineblanking method which seems to be optimal is indicated the production process.

Optimization of laser fusion cutting of coated aluminum sheets
Pokorák, Milan ; Hála, Michal (referee) ; Mrňa, Libor (advisor)
The thesis primarily deals with the optimization of laser cutting center for coated aluminium sheet cutting and with the subsequent comparison of measured results and a sample made using waterjet cutting. The thesis is divided in two parts, the theoretical part followed by the practical one. The theoretical section is concerned with the unconventional technologies used, with their general analysis, design, history and utilization for industrial appliances. Main parts of this thesis deals with classification of particular cutting principles and their specific description. The theoretical part contains also classificaton of aluminium alloy, description of surface texture measurement and explanation of basics terms used for roughness measurement. The practical section is concerned with the particular task solution and with all knowledge used for optimization and evaluation of laser cutting. This part contains the measurement results, the measured material, the machines and devices used and also the technical and economical evaluation of this thesis content. The overall evaluation of the laser cutting optimization of specific component is mentioned in the experiment outcome evaluation article.
