Production of the lightsaber handle
Bršťák, Ondřej ; Dvořák, Jaromír (referee) ; Kalivoda, Milan (advisor)
This bachelor’s thesis focuses on the design and construction of a lightsaber. Film and industrial variants have been discussed in order to create authorial designs. Out of those, one variant has been selected for further processing. Engraving has been added to the main component. This thesis describes in further detail the process of manufacture and the machines used for it with the calculation of cutting parameters. Three NC programs have been developed and implemented via the selected methods and tools. The documentation and the estimated cost of the process in context of the industrial versions have been included.

Technika gravírování laserem v nábytkářském průmyslu
Podešvová, Barbora
This bachelor thesis contains short description of the technology of laser and the art of pyrography. The concept of this study is technical description of both technologies from available resources and their aplication in furniture industry. This work is focused on two types of technologies – cutting and engraving. Both of these technologies will be used during the process of making designed element for sitting. In conclusion of this work both techniques will be compared one to another and will be evaluated their efficiency in practise.

Art deco a jeho vliv na současný nábytkový design
Jachurová, Kristýna
The bachelor thesis deals with the art deco style. It describes the main characteristics, sources of inspiration, famous works or artists, but also the technologies used in this period. The whole work is accompanied by pictures so that the reader can create a comprehensive picture. The thesis focus on technologies, both the original ones used at the beginning of the 20th century, but also the modern technologies and their possibility to use the traditional Art Deco style furniture designs. It is demonstrated in the practical part.

Design and manufacture of an engraving LED laser
Adam, Tomáš ; Slaný, Martin (referee) ; Dvořák, Jaromír (advisor)
The thesis deals with the evaluation of achieved parameters of unconventional machining methods and their current use in practice. In addition, the design and construction of the prototype of the laser engraving device is carried out. Several tests are performed on the device and are compared with similar devices after evaluation. The entire construction is designed so that no special equipment is needed and the construction could be done in each workshop.

Design for Manufacturing of an Assistant Facility for CO2 Laser
Okřina, Lukáš ; Kalivoda, Milan (referee) ; Slaný, Martin (advisor)
The main point of this thesis is a design of an assistant facility for low power CO2 lasers with a focus on a manufacturing process of the supporting metallic parts. The theoretical part of the thesis summarises the general subject-matter of CO2 laser technology, their types and industry utilisation. The thesis includes a review of main characteristics of the available assistant facilities. Main task is to design a construction of a new facility with the consecutive technological manufacturing process. The next part of this design is technical and economic evaluation in connection with mass production.

Laser micromachining
Láznička, Pavel ; Daněk, Ladislav (referee) ; Mrňa, Libor (advisor)
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.

3D engraving milling machine
Bosák, Daniel ; Vetiška, Jan (referee) ; Bradáč, František (advisor)
This thesis deals with rebuilding of a laboratory manipulator to 3D engraving machine. First part of the thesis describes the engraving technology and lists the most common types of engraving machines. Next, the initial state of the machine is analysed and modifications of mechanical and electrical equipment are suggested. Design, realisation of a control system and human machine interface are described. The Beckhoff TwinCAT programming environment is used. The last part of the thesis deals with practical realisation and commissioning of the machine. The results of the thesis can be used as an addition for lessons of Automation of Production Machines.

Project of Engraving device for graphics creation
Hložek, Vojtěch ; Richter, Miloslav (referee) ; Horák, Karel (advisor)
The objective of this master's thesis is to design and implement a system which would be able to transfer a picture (either a bitmap or a vector image) on a foundational material. The main part of the apparatus consists of a plotter controlled by two stepping motors. The engraving itself is provided by a marker mounted to a movable part of engraving head. There was a PCB created for controlling the entire system. It contains power supplies, a microcontroller and motor and engraving head controlling circuits. The second part of the thesis shows a microcontroller program and a user interface in a PC. The image is trasfered from the PC into the microcontroller where it is processed and, based on the controlling program, engraved to the material.
