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.

Milling machine CNC control
Krejčí, Jan ; Benešl, Tomáš (referee) ; Bradáč, Zdeněk (advisor)
This diploma thesis deals with rebuild of manual drill-mill machine BF20L into CNC mill machine, 3D model of that and eventual control using PLC. All axes are powered by stepper motors, with encoders, connected to control cards and industrial computer from company Beckhoff. For this control is made full switchboard, supplemented by electrical wiring diagram. Program control along with visualization is made in software TwinCAT 3. Drill-mill machine can be controlled manually or automatically by program.

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 and construction hobby milling machine
Štěpánek, Vojtěch ; Slaný, Martin (referee) ; Dvořák, Jaromír (advisor)
This work deals with comparing CNC machines. It compares components used in small hobby machines with components of large commercial machines. The work also focused on the design and construction of real CNC milling machine branded as MillVOY and findings from its testing. Emphasis during the construction is laid on minimizing costs by the use of ma-ximum of normalized parts. Lowering the cost can make these small milling machines affor-dable for any workshop.

Development of software for laboratory model of CNC manipulator
Pivoňková, Jana ; Bražina, Jakub (referee) ; Bradáč, František (advisor)
This bachelors thesis focuses on development of software for laboratory model of CNC manipulator. Research part discuss the problematics of robotic manipulators and their control systems. Furthermore, the thesis focuses on the selection of both design and software solutions, which are further developed into the final design. Lastly, the thesis deals with the implementation of the final solution and its practical debugging.
