Design of a small CNC extension
Umlauf, Petr ; Marek, Tomáš (referee) ; Pavlík, Jan (advisor)
The aim of this bachelor’s thesis it to design a fourth axis for a small CNC milling machine and a search in the field of control systems. The thesis is divided in to three parts. The first part is a search, with focuses on types of structures and their important parts. The second part describes two different designs. For the chosen one was made part of drawing documentation, a 3D model in Autodesk Inventor Professional. In the thesis were with calculations checked important parts of the design. The third part focuses on control systems that are suitable for milling machine. Mach 3, LinuxCNX and Grbl-Mega-5X were introduced.

Adaptation of the Watermill
Pavlík, Jan ; Hudec, Martin (referee) ; Klas, Roman (advisor)
The bachelor´s thesis is composed of two parts. In the first part, there is a generally discourse about small water power plants, their structural design, mechanical equipment and economical efficiency and its function is to create the basic conception of the waterwork. The second one deals concretely with the small water power plant in Crhov, that was rebuilt from the original mill by Mr. Petr König in 1990s.

Optimalization construction tube lifter of spinner machine
Jeník, Jan ; Pavlík, Jan (referee) ; Knoflíček, Radek (advisor)
The first part of this thesis describes the current technologies of mechanical spin-ning. This is a ring, rotor and air-jet spinning. The product of spinning machines is yarn, the basic material for production textile. The next section describes in detail the current state of the node manipulator lifter tube on spinning machine TORNADO J20, by concern RIETER. It describes the structure, kinematics, duty cycle and requirements for the manipulator. The following optimization options which are described more options for solutions of individual functions of the manipulator, on the end is selected by multi-criteria analysis. The best solution that is elaborate in the next section. The author has created 3-D model optimized lifter tube. Positioning mechanism maintains the current kinematics, it is very similar. But gripper was designed as a passive, thus reduce the load positioning mechanism. Optimization was performed primarily to reduce overall production costs and to reduce weight manipulator. The conclusion is a comparison of current and new solutions. There are also eco-nomic recovery to.
