Design of hydraulic press brake
Machara, Matúš ; Tůma, Zdeněk (referee) ; Pavlík, Jan (advisor)
The thesis is focused in the first part on the issue of bending and various types of press brakes In the second part, a mechanism was designed in detail to control the ram press brake during bending. The individual situations that may occur at work have been developed. Based on them and on the theoretical consideration of the deformation of individual parts of the invented solution, the individual components were dimensioned. A possible solution of the basic construction of the whole press brake according to the assignment parameters was also outlined. Finally, a recommendation for the production of this solution was mentioned.

Integration od robot in production of pressure tank for common rail system
Krejčí, Monika ; Tůma, Zdeněk (referee) ; Knoflíček, Radek (advisor)
This diploma thesis is about integration process of assembly line automation on rail assembly. In the beginning is introduced Bosch Company, then follows up theoretical part about automation and assembly lines. After theoretical introduction continues description of current state of rail assembly and choice the best line for automation and its detailed description. After that, the work deals with finding of the best solution for line automation. Found solutions are evaluated using the decision matrix. After the best one of them is chosen. There is also calculation of investments, because the one of important conditions is, that payback period has to be less than two years. Next step is choice of the most suitable supplier and integrator, which can cope with all requirements. At the end of thesis is analysis of risks done and thanks to this, are potentials for improvement of workplace safety found.

Design of end effector for a robotic cell
Machala, Lukáš ; Pavlík, Jan (referee) ; Tůma, Zdeněk (advisor)
This Master´s thesis deals with the design of end effectors for object manipulation within robotic cell located at the Department of Production Machines, Systems and Robotics, Brno University of Technology. The theoretical part of the work is devoted to a summary of the current state of knowledge in the field of end effectors. The practical part deals with draft of several variants of the solution, from which is chosen optimal variant by the method of multicriteria analysis, after which follows the construction of individual end effectors. The work includes individual 3D models of these end effectors and a rack for their storage, the work also includes assembly and part drawings. The work ends with an economic evaluation, discussion of achieved results and a conclusion.

Robotized glue application on small parts
Jochec, Tomáš ; Tůma, Zdeněk (referee) ; Vetiška, Jan (advisor)
This bachelor thesis highlights the current state of robotics in the world and is focused on the application of glue on small parts by robots. The main goal is to develop a design for the workplace, using the work of a robot and its further digital commissioning. The work is divided into four parts. The first part is a literature search that deals with current issues of robots and dosing systems. The second part is a system analysis, where we apply the knowledge from the editorial part to the creation of a robotic workplace. In the third part, the digital commissioning of the workplace using RobotStudio software takes place. The end of the work is devoted to the discussion and conclusion of the achieved goals.

Use of Head-mounted displays in risk management for machine tools
Jelínek, Martin ; Kotek, Luboš (referee) ; Tůma, Zdeněk (advisor)
This diploma thesis deals with the design and technical possibilities of VR headsets and their application in mechanical engineering, specifically in the field of risk management in machine tools, using experience from other areas and history. The practical part of the thesis comprises a risk analysis carried out on a single selected machine (vertical machining center) by means of checklists and virtual technologies. The risk analysis techniques used are subsequently compared and evaluated. The results are then assessed and a proposal for the use of virtual reality in practice is put forward.

Robotic workstation for silicon filling of part of “Valve cartridge”
Černý, Jiří ; Tůma, Zdeněk (referee) ; Knoflíček, Radek (advisor)
This diploma thesis is focused on robotized technological workstation (RTW) for production of “Valve cartridge” product. The production workstation, studied in the diploma thesis, is located at IMI Precision Engineering company and is focused on silicon filling. In the introduction a present workstation is evaluated and a present status of industrial robots and robotized workstation is analyzed. In main part of the thesis two solutions for robotic automation are designed, with respect of assigned parameters. The final solution is chosen by method of multicriteria decisional analysis. Project documentation is created for chosen variant including manipulation work cycle and block diagram of RTW control. The thesis includes calculation of capital return. At the final part of the thesis ergonomics and safety of workstation is analyzed; the risks of robotized technological workstation components are also evaluated. Technologists and quality engineer requirements are taken into account during working on the thesis.

Construction of a single-purpose machine for automatic testing of pneumatic fittings
Tejkl, Michal ; Štěpánek, Vojtěch (referee) ; Tůma, Zdeněk (advisor)
The subject of this diploma thesis is the design of a single-purpose machine for automatic testing of pneumatic fittings. Pneumatic fittings used in brake systems are subject to high technical requirements and 100% tightness control in production. In this case, manual testing is not effective and the goal is to automate the process. The theoretical part presents pneumatic mechanisms, analysis of the tested pneumatic fitting with technical parameters, the possibility of tightness testing, use of sensors, and rotary tables. In the practical part, a systematic analysis of the problem was performed, according to which the overall design proceeded. Subsequently, the design of the complete machine containing individual nodes is processed, supplemented by the necessary calculations. The conclusion of the thesis contains an evaluation of the whole project.

Evaluation of present technologies in ensuring functional safety of machinery
Smetana, Štěpán ; Tůma, Zdeněk (referee) ; Zahálka, Jiří (advisor)
This bachelor’s thesis is concerning functional safety as a whole. The first part of the paper will provide a description of what we can imagine under the term of functional safety and why we should pay attention to it. The document also includes introduction of safety components used in a frame of functional safety and its brief description. You can find here methodical approach to calculation of performance level PL and safety integrity level SIL, this calculation is shown on an example of an emergency stop function.
