Technology of product machining on CNC machines
Brázda, Jiří ; Kalivoda, Milan (referee) ; Osička, Karel (advisor)
This diploma thesis deals with a technology of production milling of sample component “ending of generator shaft” by CNC milling in environment of small company. At first common aspects of CNC machines, technology of CNC milling and technology of construction are introduced. Possible problems with milling of sample component are analyzed and their possible solutions are presented. Next technology of CNC milling with operating program for CNC lathe (HAAS SL20) and CNC milling machine (HAAS VF3), production of component in small company with necessary documentation in technology procedure are projected. Using of operating systems HAAS, Fanuc and HEIDEHAIN are compared. Using of cutting tools and cutting condition for component milling is projected. Finally timing of operations and financial calculations necessary for small production of sample component is proposed.

Measuring cycles in control systems of CNC machines
Hamřík, Jiří ; Jaroš, Aleš (referee) ; Gregor, Lukáš (advisor)
In the first two points, the bachelor's thesis focuses on the comparison of CNC and NC machines and methods of control and programming of CNC machines, a description of the control system of CNC machines from selected producers and the characteristics of measuring cycles. Two producers were selected to describe the technology of measuring tools and workpieces using probes. In the third point of the bachelor's thesis, a practical demonstration of measurements with tool and workpiece probes from RENISHAW is performed. A tool correction was performed followed by measurement of the workpiece with a probe. For statistical evaluation, digital micrometer measurements were added, including comparison and evaluation of the obtained results.

Multi-Way robotic wheelframe
Krsek, Jiří ; Kopečný, Lukáš (referee) ; Šolc, František (advisor)
The master's thesis deals with a theoretical analysis of properties of a multi-way wheelframe and a selection of an appropriate method for the human operator control. Based on the analysis will be designed hardware and software of the control unit for controlling the movement of the robot's multi-way wheelframe. The electronic system will ensure a real-time processing the operator's instructions to control signals for the motors that will drive and implement the required angles of two driven wheels of the chassis. The proposal also reflects a sufficient equipment with input-output channels for any subsequent extension of additional sensors for testing the autonomous robot operation.

Controling the dust exhaust of smeltery for recyclation of aluminum waste
Jakubský, Ondřej ; Nadrchal, Zdeněk (referee) ; Trnka, Vladislav (advisor)
The work deals with controlling and visualizing technology of dust exhaust of smeltery for recyclation of aluminum waste. In the first part of the work are analyzed the different ways of automatic control. Based on the analysis is proposed control system configuration, algorithm of control, communication interfaces and sensors of alarm, measurement and regulation. The second part deals with visualization and remote administration of control system. On the basis of selection for the visualization software is designed and implemented a system that provides visualization of technology, the archiving of measured operating values, events and errors.

Application for Simulation of PROFINET Controller
Mazurek, Tomáš ; Holkovič, Martin (referee) ; Kreslíková, Jitka (advisor)
This bachelor's thesis deals with development of an application simulating the Profinet controller. The main function of such controller is to establish an application relation with a device, which is communicating via the Profinet technology. Through the application relation then takes place the entire exchange of information. The goal of the controller simulation, run on a desktop computer, is to facilitate the testing of input/output devices connected to the system via Ethernet interface. The resulting application allows to monitor and modify the communication much easier than the real control system.

Usage of Modern Methods for Increasing Reliability of Control System Implementations
Szurman, Karel ; Mičulka, Lukáš (referee) ; Kaštil, Jan (advisor)
At avionics control and critical systems is necessary guarantee a minimal level of fault tolerance and their high reliability. On the electronic components in these devices has an undesirable influence environment conditions and mainly cosmic ray. In this paper are described the most common failure types of semiconductor components and devices together with modern methods which can be increased the system fault tolerance and its overall reliability. There are introduced aspects of the avionic systems design due to finally certification and ways to evaluate its safety. This thesis describes design and implementation of the CAN bus control system for the FPGA platform which uses the CANAerospace application protocol. Created system design is improved by the TMR architecture. Fault tolerance of both system version is tested by the SEU framework which allows using the dynamic partial reconfiguration generate an SEU failures into running FPGA design.
