Digital commissioning of a robotic production system for resistance welding
Šuba, Marek ; Bražina, Jakub (referee) ; Vetiška, Jan (advisor)
The subject of this diploma thesis is the simulation and digital commissioning of a robotic production system for welding elements such as studs on sheet metal parts. The basis of the work is search of information related to industrial robots, PLC control, tools used for welding, fixtures, manipulators, sensors, safety and protection elements commonly used in such production systems. The second part of the work deals with the given problem and it is a virtual commissioning of the given concept of a robotic production system. This means creating its simulation model in the Process Simulate environment, selecting robots, creating robotic trajectories, collision analysis, creating sensors, signals and optimization. Last part includes the connection of the simulation model with the software S-7PLCSIM Advanced and TIA Portal, the creation of control PLC logic in the form of a program, visualization and verification of their functionality using the above-mentioned connection with the simulation model.

Design of welding cell
Šuba, Marek ; Kočiš, Petr (referee) ; Vetiška, Jan (advisor)
The topic of this bachelor's thesis is the design of a robotic cell for spot resistence welding of sheet metal parts. The base of this thesis will be the research of industrial robots, spot welding guns, welding fixtures, robot grippers, sensors and safety precautions used in such robotic cells. Second part of the thesis contains few concepts regarding the robotic cell itself and the choice of the best one for the situation at hand. Third part of the thesis contains the choice of welding guns, construction of the welding fixtures and possibly even robot grippers for the given metal sheet parts. In the last part of the thesis comes the simulation of the welding process in RobotStudio (software from ABB), check whether the robotic cell meets the requested production time needed and a final assessment of the results.

Automatic Generation of Scanning Positions for Sheet Metal Parts Digitization
Koutecký, Tomáš ; Druckmüller, Miloslav (referee) ; Matula, Pavel (referee) ; Morovič,, Ladislav (referee) ; Brandejs, Jan (advisor)
This thesis deals with the development of a new methodology for automatic generation of scanning positions based on a computer model of the part for digitization of sheet metal parts. Manufacture and related inspection of sheet metal parts are closely connected to automotive industry. Based on increasing general requirements on accuracy, there is also a requirement for accurate inspection of manufactured parts in serial-line production. Optical 3D scanners and industrial robots are used more often for that purpose. Measuring positions for accurate and fast digitization of a part need to be prepared as the manufacturing of the new part begins. Planning of such positions is done manually by positioning of the industrial robot and saving the positions. The planning of positions proposed by this methodology is done automatically. A methodology of positions planning, their simulation for true visibility of the part elements using reflectance model and a simulation of the positions for robot reachability is presented in this thesis. The entire methodology is implemented as a plug-in for the Rhinoceros software. High reduction of time in positions planning compared to the manual approach was observed in the performed experiments.

Effective use of 3D Cad systems in the field of process engineering-II
Marek, Tomáš ; Dvořák, Radek (referee) ; Pavlas, Martin (advisor)
The aim of this work was adoption and description of correct technigues of creation basic mechanical components under CAD system SolidWorks. This gained know ledge was then used for creation of library of standard parts used in process engineering with focus on design of pipeline systems. Conceretaly, the assembly of flouged circular Y-branch for duct system was solved. The possibility for its further modification of dimension as well as transformation into parts of similar shape was analysed. Finally, user manual describing the user interface and necessary design procedures was prepared.
