Design and realization of CO2 laser with power up to 100W
Šrenk, Jakub ; Dvořák, Jaromír (referee) ; Slaný, Martin (advisor)
This work is focused on the problematics of small CO2 lasers and their possible use for commercial production. The first part describes devices available on the market and evaluation of their parameters. The practical part specifies the parameters that arise from the potential use of technology. Based on these parameters, design of the machine and its complete mechanical design are elaborated. Furthermore, the experimental part deals with the design of structural components, control system, electrical systems and in general a complex technical-technological solution of the equipment, including economic evaluation of the design. Part of the work is also the construction of the machine itself, including activation, adjustment and debugging for the considered production. The constructed machine was subject to testing to ensure required quality of production.

Compare weld from CO2 laser and fiber laser
Leidorf, Michal ; Kubíček, Jaroslav (referee) ; Mrňa, Libor (advisor)
The project compares the technology of welding of CO2 laser and fiber laser in terms of engineering study, the welds will be made by same welding conditions on two materials (S235JRG2 a X5CrNi 18-10), by using different protective gases (Helium and Argon). In the terms of literal background research both the technologies and questions of laser welding are described. The geometry of welds is carried out in the experimental part. The final results of the experiment are concluded at the end of the diploma thesis.

Analysis of the surface after laser cutting
Narovec, David ; Sedlák, Josef (referee) ; Osička, Karel (advisor)
This diploma thesis discusses laser cutting and the consecutive surface treatment of cut parts. The theory of laser cutting is described in the first part of this thesis, including laser history and the laser emergence principle. Cut parameters and the influence of the laser cutting on the material are described later on. The next part describes the laser cutting technological possibilities and other laser technology utilization options are outlined. In the last theory part, metal surface treatment used in the experiment is covered. Coating thickness is evaluated in the practical part of this thesis, as well as roughness, microhardness, chemical microanalysis and metalography. The evaluation of the results achieved, and optimal surface treatment execution suggestions are addressed in the last part of this thesis.

Use of laser machines for metal cutting technology
Novák, Petr ; Osička, Karel (referee) ; Kalivoda, Milan (advisor)
This bachelor thesis deals with laser cutting technology and its use in industry. A large part of the work consists of theoretical research, dealing with the characteristics of individual types of laser machines and their use for industrial applications, especially for metal cutting. Furthermore, the work is focused on the theory of this technology and suitable materials. The work also deals with two companies, which represent typical use of a laser machine. In the experimental part of this thesis the manufacturing process of component is created based on a survey of the use of laser machines.

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.

Proposal of a Marketing Strategy to Increase the Use of Production Equipment in a Selected Company
Vozák, Tomáš ; Havíř, David (referee) ; Chlebovský, Vít (advisor)
The diploma thesis focuses on the marketing strategy of a small family business and is divided into three main parts. The first part describes the theoretical background of marketing and is important for a better understanding of the subject. In the second part of the thesis an analysis of the internal and external environment of the company is made on the basis of the theoretical knowledge. The conclusions from these analyses are then used in the third part of the thesis, which is focused on the formulation of specific proposals for improving the marketing strategy of the company.

Design of Technology for Cutting and Engraving of Rotary Semi-finished Products for the CO2 Laser
Šrenk, Vojtěch ; Dvořák, Jaromír (referee) ; Slaný, Martin (advisor)
The thesis deals with the design and implementation of a rotary axis in a CO2 laser cutter for the ability to cut and engrave rotary workpieces. The thesis is focused on identifying several similar available known competitive solutions, for which the pros and cons were evaluated. Based on the findings, suitable parameters were selected to achieve maximum versatility of the proposed system. Versatility in this respect is related to the ability to cut and engrave the widest possible range of rotary workpieces. The thesis also describes the design solution, axis assembly procedure, production design and production of individual components using 3D printing technology (FFF), selection of suitable standardized components and the actual implementation. The conclusions then focus on the proposed solution from an economic and technical point of view.
