Position control of cross-table dedicated manufacturing machine
Plocek, Jaroslav ; Vetiška, Jan (referee) ; Houška, Pavel (advisor)
The bachelor thesis treats the drive solution of the two axis cross-table of a single-purpose manufacturing machine. The first chapter analyzes the concept of drives and compares different variants using either a direct linear drive or a ball screw with a rotary servo drive. The thesis further deals with sizing the motor and the power unit assembly and the description of the whole measuring system. The structure of cascading position controller, its description and the calculation of current and speed control loops is covered in the next part. The last section discusses practical settings of all control parameters.

Digital commissioning of a robotic production system for sandblasting technologies
Dvořák, Vít ; Szabari, Mikuláš (referee) ; Vetiška, Jan (advisor)
This bachelor thesis deals with the digital commissioning of a robotic production system for blasting aluminum castings. The introductory theoretical part discusses the technology of digital commissioning and blasting technology. The practical part is divided into several parts. In the first part, a system analysis is created, which sets out the conditions that the system should meet. The following is a conceptual design of a robotic cell, selection of individual system devices and determination of technological parameters. In the third part, a technological jig is designed, which is used to set up the blasted part inside the cabin. The last part deals with the creation of the robot path and the creation of the basic logic of the production system in the ABB RobotStudio program.

Impact of conventional compensation to the volumetric accuracy of the machine tool
Žák, Zdeněk ; Vetiška, Jan (referee) ; Holub, Michal (advisor)
This thesis solves the impact of conventional compensation to the volumetric accuracy of the CNC machine. It is therefore a practical research work, where are in the theoretical introduction mentioned requirements for machine tools, the types of errors that can occur on three-axis kinematics, compensation for the control system Siemens Sinumerik 840D sl and devices by means of which are these compensation under the work formed and subsequently verified. In this work can be seen the measured values and graphs from each measurements, a detailed analysis of the results and drawing conclusions from these results.

Digital commissioning of a robotic production system for laser cutting
Žaludek, Jan ; Kočiš, Petr (referee) ; Vetiška, Jan (advisor)
This diploma thesis deals with digital commissioning of a robotic production system for laser cutting. First part of this thesis sums up teoretical knowledge of virtual commissioning, fundamentals of laser and laser cutting and system analysis of such a workplace. In practical part of this thesis, the workplace was designed including the workpiece clamping. The design and the digital commissioning itself was mediated by the software RobotStudio. In the programming language RAPID a control program was made and tuned. The workoplace was then virtually commissioned. For easier handling a user interface on FlexPendant was made.

Control units for small EC motors with universal software interface
Vetiška, Jan ; Hadaš, Zdeněk (referee) ; Houška, Pavel (advisor)
This graduation thesis deals with the design and realisation of the universal control unit for the electrically commutated motor ( EC motor). Was to accomplish the market research of control units for EC motors and compare of parameters of control units with requirements for the universal control unit of EC motors. From the research ensued that on the market it is no unit with the open system which could enable substitute particular control loops by own loops. Based on this evidence it was approached to own construction of the universal unit. For the design it was used the access hardware in the loop a software in the loop. It was performed the design of particular sections of the unit, manufactured the power section and this power part was tested by the help of the developmental and simulation software Labview. Furthermore it was proceeded for the realisation of the integral control unit and for supplementation of the existing software of the control unit about appropriate drivers and it was undertaken the modification of the control algorithm for the need of EC motor. On the end of this project we tested achieved parameters of the control unit.
