Connectivity control system to virtual reality system
Holešovský, Jiří ; Tůma, Zdeněk (referee) ; Bradáč, František (advisor)
This thesis deals with options of connecting the real control system to the immersive virtual reality system. Options of moving an object in IC.IDO are mentioned in the first part of the thesis. The theoretical part deals with commercial types of gaining data from control systém Sinumerik 840D sl and with programmable types of gaining data which means that there is no need to buy other licenses or software. Two g-codes were made in the experimental part. The first one provides feed of the machine in x axis and the second one reads position of the x axis of the machine and actual times. A script for IC.IDO which moves a model in IC.IDO exactly as the machine moved was written.

Extension of the 3D printers for special print head
Helienek, Matúš ; Pavlík, Jan (referee) ; Bradáč, František (advisor)
This thesis deals with improvement of 3D-manipulator which is currently used for 3D printing. The improvement involves adding a new printer head which will be able to acquire various colors by mixing up to three materials. Furthermore, device is extended with milling as a finishing process responsible for better surface quality of printed object.

Database Assistance of Risk Assessments
Sýkora, Ondřej ; Blecha, Petr (referee) ; Bradáč, František (advisor)
This diploma thesis is concerned with creation of a computer program for management of technical documentation and its retrieval over a network. The program allows keyword search in documents in a database, either in all of them or in those selected according to given criteria. Any document found is then available for viewing. Moreover, users can create custom shortcuts to arbitrary places in documents for quick access. The program has been written in the PHP scripting language and employs an HTTP server, thus it can be used not only on a local area network but also remotely from other places with internet connectivity.

Design of coaxial high-speed gear reducer
Neklapil, Libor ; Ing. Tomáš Hubáček, Ph.D (referee) ; Bradáč, František (advisor)
The thesis deal with design of coaxial high-speed gear box for small-scale turboshaft engines. At the beginning a study of problems was performed and for design concept was elected version of single-shaft turbo-engine with electric generator. Kinematic diagram, type of gear design, material and lubrication method was designed. Further was solved proposal of basic gearing parameters, choice of the number of tooth and basic proposal calculations were performed. Was performed check calculation of gearing, calculation of bearings durability and was processed design documentation in required range. Designed gear reducer has two stage with three coutershafts, that are deployed evenly about main axis of reducer. First stage is gear with external gearing, second stage with internal gearing. The thesis may be used as a template for next similar gear reducers design.
