A software interface for a laser tracker user application
Kozáček, Peter ; Kovář, Jiří (referee) ; Knobloch, Josef (advisor)
For assembly of product machine is necessary to evaluate a geometric accuracy of individual functional parts of the machine. This process is very demanding and time consuming. One of the reasons of mentioned problems is the lack of software (adaptation) for measuring of the accuracy of geometrical precision. This theses (diploma work) focuses at facilitating the development and creation of own application based on customer requirements and for measuring geometric accuracy with the Laser Tracker AT901 from Leica company. The aim is to create a basic application suitable for measurement of geometric accuracy, which would speed up this process, would be user-friendly, simple and open for further expansion.

Continuous conductivity measurement of produced copper wire
Kozáček, Peter ; Hadinec, Michal (referee) ; Klusáček, Stanislav (advisor)
My project is about possibilities of conductivity measurement of copper wire. I focus on basic principles of conductivity measurement and their applicability for continues measurement. Also I focus on proposing methods which would be the most appropriate for continuing measurement of conductivity. Each individual method is based on basic physic principles. I compare these measurement methods from different important industrial point of views in this project.

Control algorithms for BLDC motor for low speeds
Kozáček, Peter ; Pohl, Lukáš (referee) ; Veselý, Libor (advisor)
The diploma work concerns on an issue of data collection of speed and electrical angle based on informations from Hall sensor with the necessary resolution for control of BLDC motor. Specifically, concenred on a section with low speed. Most of moors use Hall sensor for detecting speed and position of the rotor. At low speed section, becomes the situation when we can not determine the position of the rotor with (the) required (sufficient) resolution, this situation creates a „wince“ in the control (ripple torque). The task is to design and evaluate the possibilities of the algorithm for control and acquisition speed and rotor position with the required accuracy.

A boring head for a drill
Suda, Martin ; Kozáček, Peter (referee) ; Kočiš, Petr (advisor)
This bachelor thesis belongs to the field of machine tools and accessories. It deals with machining method of boring and mainly with instruments used for boring. The thesis is divided into a research and a practical part. In the practical part a boring head for drilling with eccentricly placed spindle is solved. Its movement on the circle mills the hole.
