Moderní trendy v technologii kovoobrábění
Dostál, Jiří
This bachelor thesis deals with the issue of metal cutting and automation of manu-facturing processes. The first part is a presentation of some of the theories and methods of cutting and non-cutting operations. The basis and principles are described. Following part focuses on cutting materials, its basic division and expected progress. Next part describes distribution of machining centres and the market presence. The attention is also focused on robotization and its use in engineering industry. The most perspective and modern technology appears to be the non-cutting operation, which is described in this thesis.

Flow Measurement of Hot Dusty Gas
Dostál, Jiří ; Štohl, Radek (referee) ; Šedivá, Soňa (advisor)
The bachelor thesis deals with the measurement of hot dusty gas. The introduction outlines the problems of measurement. Another part of the work contains a theoretical introduction to the measurement of gas flow. In successive chapters the basic principles and characteristics of suitable methods for measuring the hot dusty gases are described. Finally, the function blocks are implemented in the Simatic STEP7 for calculation of volume flow rate and blocks are tested on PLC.

Technological process simulation
Dostál, Jiří ; Veselý, Libor (referee) ; Malounek, Petr (advisor)
This paper deals with a design of an inverted pendulum model and its controller in Matlab/Simulink, a conversion of the model and its controller to the ANSI C language and its implementation to B&R PLC's. The source code for B&R PLC's is generated automatically by the B&R Automation Studio Target for Simulink library. The first part deals with the design of a mathematical model of the inverted pendulum and its simulation in Matlab/Simulink, followed by a design of a LQ controller for this model using Matlab functions and a description of the B&R Automation Studio Target for Simulink library. The last part of this paper deals with the implementation of the model and its controller into two separate B&R PLC's, which are networked with the Ethernet Powerlink industrial fieldbus and it also describes visualizations that were designed for operating the system.

Acyclic Profinet Communication between Sinamics Converters and Simatic S7-1200 PLCs
Dostál, Jiří ; Janda, Karel (referee) ; Pásek, Jan (advisor)
This paper deals with acyclic communication of Siemens Simatic S7-1200 PLCs and Sinamics drives on the Profinet industrial bus. Various possibilites of communication of the devices in accordance to the PROFIdrive profile is presented. General Proxy FBs for acyclic read/write of the drive's parameters are implemented. Together with other two FBs, that make use of acyclic communication to read the drive's fault buffer and to adjust an absolute encoder, an application with visualization for a simple positioning and for a demonstration of the Proxy FBs functionality is presented using a demo box.
