Technology of Laser Cutting
Strouhal, Lukáš ; Dobrocký, David (referee) ; Sedlák, Josef (advisor)
The master’s thesis deals with laser cutting technology and application in the industry. The first part of the thesis describes principle of laser beam creation, division and application of lasers in industry. The Experimental part is focused on cutting the workpiece using a laser and water jet in company named SMR Plus s.r.o., sample preparation and examining the structure of workpiece. Surface structures are compared with workpieces from water jet at the end of thesis.

Laser Plotter for Cutting Steel Plates
Dokulil, Marek ; Šimek, Václav (referee) ; Crha, Adam (advisor)
This diploma thesis is divided into two main parts. The first section is dedicated to the history and development of the laser technology. The second part describes all individual types of laser technology which are used in the industry nowadays. The next section follows with the research of various laser devices which serve mainly as a cutting tool. This knowledge gathered in the previous part was used to create the next part including the own conception of the machine. The second half of this diploma thesis deals with a research of software available at the market today. Eventually, after summarizing the characteristics of each software, the new concept and implementation of own software are made. In the final section, there are mentioned the possible extension and available upgrades. The reader should be able to create his/her own conception of the laser device and software after reading and understanding this paper.

Diamond wheels and their use in the stone industry
Skryja, Jan ; Kolář, Ladislav (referee) ; Jaroš, Aleš (advisor)
This bachelor thesis deals with stone sawing during stone processing. It is divided into theoretical and practical parts. In the theoretical part diamond blades, the sawing process and stone extraction are described. The practical part is focused on the wear of circular saws in granite circular sawing. The wear is determined for two diamond cutting blades made by different manufacturers and is determined by the blade weight loss and segments height loss as a function of time. Both measured values show linear dependence. The results are the basis for a future comparison of the two diamond blades on the economic side, which is not the subject of this work.

Parameters of the laser beam
Hort, Zbyněk ; Kolář, Ladislav (referee) ; Osička, Karel (advisor)
The diploma thesis consists of the three main parts. The first part deals with the theoretical description of the laser technology and other unconventional technologies. In the second part, the thesis is focused on testing the parameters of the laser and evaluating the most suitable parameters. In the last part the diploma thesis deals with comparison of unconventional technologies in terms of cut quality

The laser beam use in a production of parts for manipulating technique
Polák, Marek ; Kalivoda, Milan (referee) ; Osička, Karel (advisor)
This Diploma thesis trests of laser and his localisation in production sphere. It briefly describes principle, function and possibilities of laser, mainly laser technology by machining. It tafgets the possibilities of laser by cutting. The diploma thesis was elaborated in conjunction with the company Manex & Co, a. s., producer of handling systems. It disposes of CNC cutting machinery, which is fully engaged. A chain gear from ČSN 41 1363 was produced in terms of this diploma thesis.
