Design and manufacturing of an engraving LED laser
Hlaváček, Petr ; Kalivoda, Milan (referee) ; Dvořák, Jaromír (advisor)
The bachelor's thesis is divided in two main topics. In first one it characterizes what unconventional machining methods are and divides them into groups according to the material removal effect. Each method is always simply and briefly explained. The purpose of this part is to introduce the unconventional technologies and their use in mechanical engineering. Second major topic follows comparison between beam methods and is dealing with the design and construction of a laser engraver. The goal is to build a prototype that allows not only engraving but also cutting into materials such as cardboard. The primary purpose of this machine is the production of kits for model railroad. The last chapters are about economic evaluation and comparison between made prototype and commercially sold engraver.

A COMPARISON OF THE WATER JET CUTTING AND LASER TECHNOLOGIES
Chamrad, Jakub ; Zlámal, Jan (referee) ; Píška, Miroslav (advisor)
The thesis is focused on the introduction of non-conventional technology into the manufacturing workplace, mainly water jet and laser cutting. The first two chapters are research about water jet machining and laser. A practical part of my thesis was carried out with the assistance of Honeywell and involved comparing the efficiency of an older laser cutting machine against and new one for water jet machining.

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.

The proposal of the base body for wall clock using unconventional methods
Janás, Milan ; Zemčík, Oskar (referee) ; Dvořák, Jaromír (advisor)
This thesis describes the design and manufacture of the basic body clocks using unconventional methods. The work consists of two parts. In the first unconventional methods are discussed in theory explaining the basic principles and methods of use of different methods and their advantages and disadvantages. More details are described two methods, laser and water jet, which are used in solving the practical part of this work. The second part describes a practical solution of the base body using a laser and water jet. The methods are examined in terms of suitability for use and are analyzed their advantages and disadvantages with respect to the manufactured part. In conclusion, these methods are compared from an economic perspective, production time, affecting surface and achieved accuracy. The outcome of this work is to compare the methods used to produce the base body and the assembly of functional clocks.

Camera system with wire EDM
Gvizd, Michal ; Mouralová, Kateřina (referee) ; Osička, Karel (advisor)
The thesis discusses an unconventional technology of wire-cut electro discharge machining. In the beginning there is a description of the basic principle, the fundamentals of electro discharge machining and its technological application. Further chapters characterise the wire-cut electro discharge machining, the wire electrodes used, the main parts of the machine, the cutting conditions and the advantages of this technology. The practical part is focused on the possibilities of the camera system during the production on a wire cutting machine and the comparison of nowaday´s machines in the manufacture of precise cutting tools in the middle-sized tool-room.

Trends of development water jet machining
Brym, Radek ; Slaný, Martin (referee) ; Osička, Karel (advisor)
In diploma thesis there is elaborated the analysis of assumed development of water jet technology and there is analyzed the level of water jet method in production. There are introduced the possibilities of new applications of water jet machining and the possibilities of it’s future development. There is think over the enlargement of this method in next 5 years. Simultaneously there is solved the question of techno economic operation severity of this technology.

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.
