Design of magnetic drilling machine
Jun, Lukáš ; Tůma, Zdeněk (referee) ; Tůma, Jiří (advisor)
The thesis is focused on a specific type of drilling machines, the magnetic drills press. These machines are typical for their magnetic base and are used mainly to machine magnetic materials, nonetheless, with suitable accessories, also the non-magnetic materials can be machined. The first part of the thesis begins with a description of the individual parts of the magnetic drill, their types and an overview of the accessories. The second part of the thesis contains the design of the drill itself. Cutting conditions for a 20mm twist drill and a 60mm annular cutter are defined. Based on the cutting conditions the motor is selected, then the design of a gearbox, selection of bearings and the whole assembly of the gearbox is described. Calculations of gearing, 3d model, drawing of assembly and two parts are attached with the thesis.
Virtual reality in design of production machines, systems and robotics
Jun, Lukáš ; Tůma, Zdeněk (referee) ; Knoflíček, Radek (advisor)
This bachelor thesis in the first part describes history and development of the virtual reality, following part brings overview of the different types for virtual reality, possibilities of usage, specifies all requirements and constrains with needs to be met for creation of realistic virtual reality. This thesis also contains areas about human vision, sound and touch, mainly focusing on how to confuse them using computer controlled technology. Thesis also brings an overview about negative consequences of virtual reality on the human health. Last part of this thesis contains an overview of basic software tools for creation of virtual reality and in the end brings two examples of usage virtual reality in mechanical engineering.
Development board with 32-bit ARM-based processor
Jůn, Lukáš ; Šebesta, Jiří (referee) ; Frýza, Tomáš (advisor)
The content of this thesis is to create a detailed description of 32-bit ARM-based processors. Reader will be inform about the each one of the family of ARM-based processor, about the options of creating applications for these CPUs. The Applications are commonly developed by using the C/C++ language. This text also deal's with the development environments. These tools are making easier the development of new applications. This thesis also contains a complete design and description of development board with Atmel AT91SAM7S64 MCU (with sample of source code included).
