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.

Suggestion of convenient technologies of production for submitted flat sheet metal part
Chaloupková, Lucie ; Podaný, Kamil (referee) ; Špaček, Jindřich (advisor)
The project is elaborated in frame of engineering studies branch 2303T002. The project is submitting suggestion of convenient technologies of production for submitted flat sheet metal part 11 375. There are proposed a number of variants of production method, namely: production on sequence shearing tool, production by means of plasma machine, laser machines and machines for watejets cutting. Particular part is designed for the production quantity of 380 000 pieces per year. Based on the literary study of the shear and calculations, there were designed shearing tool for given part. For this tool the press CDCH 3000 P was selected (producer HESSE+CO Maschinenfabrik GmbH), with nominal force 3 000 kN. In the work there are included necessary calculations for all variants including technological and economical 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.

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.

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.
