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.

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.

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.
