Abstract:
This study deals with technology of abrasive water jet material cutting and influence of cutting head feed rate on surface topography of cut walls with regards to roughness. Eight parameters were chosen based on the CSN EN ISO 4288 standard representing quality of surface after AWJ cutting. When AWJ cutting the chosen material – commercially pure ASTM B265 grade 2 titanium – feed rate was being changed and in order to obtain information about each parameter´s distribution in various depths of the cut, surface composition was evaluated. It was found out that feed rate has significant influence on surface and that the profile elements´ width grows when increasing the feed rate and cut depth. Furthermore, two selected feed rate results were compared to laser beam technology and conclusion for the selected material was made that AWJ cutting is more preferable due to final roughness and no heat affect on the material.

Abstract:
This thesis deals with lasers, their general theory and application. Then a theoretical part describes laser micromachining and engraving. Experimental part of thesis deals with several experiments performed by powered fibre laser which is not primarily intended for the field of micromachining. Experiments were mainly evaluated by several types of microscopes where the amount of removed material was appraised. By particular experiments removed material was in accordance with used working parameters of laser and a significant role plays machining material. It emerges from the experiments that for the field of laser micromachining and engraving shorter pulses are more suitable (minimal pulse duration was 1 ms in experiment) and it is connected even with a way of removing material. Applied powered laser can be used for micromachining in specific fields of production.

VACULA Jakub: Optimization of plasma cutting parameters Diploma thesis of the attendance engineer´s study – Mechanical Engineering, specialization Machinery Technology. Academic year 2008/2009. Faculty of Mechanical Engineering of University of Technology in Brno, Institute of the Manufacturing Technology. The Diploma thesis is concerned with the thermal division of a material, concretely by the plasma cutting. It monitors the operational parameters influence of this process to the result quality of cut and the purpose is to optimize these parameters from the qualitative standpoint. The experiment was executed at the plasma cutting equipment Fine Focus 800 of the company KJELLBERG with the utilization of the material S 690 QL. On the base of the literary study of the thermal division of the materials problems it was also described the comparison of the plasma cutting with the method of the division of materials by the oxygen, both from the point of view of the quality, and from the economical point of view.

Abstract:
The dissertation thesis is focused on the optimization of control parameters of an EDM machine; the subject of optimization is cutting speed and surface topography. The first part of the thesis contains a research study on the technology of electrical discharge machining with the attention paid to the optimization methods use for control parameters of this process. The second part of the thesis is focused on real application of knowledge gained from studied sources. Here, a design of experiment aim at optimizing the parameters of the EDM machine is designed and carried on to maximize the cutting speed with the highest possible surface quallity. The result of the work is to build adequate regression models and find the optimal setting of machine control parameters.
