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.

Measurement of roughness of the laser cutting edge
Pokorák, Milan ; Hála, Michal (referee) ; Mrňa, Libor (advisor)
This thesis primarily deals with the laser material cutting and with the subsequent evaluation of roughness of the cutting edges. The thesis is divided in two parts, the theoretical part followed by the practical one. The theoretical section is concerned with the introduction to laser technology and with the basics of roughness measurement. It contains the history of laser, its construction and its physical principle. It also deals with the description of laser types and laser technologies. An important part is about the surface texture, which includes basic terms and methods of roughness measurement. The practical section is concerned with the comparison of roughness of the cutting edges. They were measured on S235JR steel samples with the value declared in ČSN EN ISO 9013 standard. This part contains the measurement results, the measured material and also machines and devices used. The overall evaluation of the practical measurement is mentioned in the final experiment outcome evaluation.
