Robotic machining with external tool
Ryvol, David ; Pochylý, Aleš (referee) ; Kubela, Tomáš (advisor)
The goal of this final thesis is to evaluate the performance of chosen CAM software in robotic deburring of cast parts while using external tool. For this purpose, an analysis of program’s functions was carried out and toolpath-making strategies were compared. The most appropriate strategy for mentioned technology was chosen based on this analysis. The generation of a toolpath was described on the example of real part from automotive industry. In order to simulate real machining process, a model of workspace was created, proper tool with spindle was selected and a method of clamping the workpiece was designed. A postprocessor was created, and so was the robot program, after successful simulation, as a foundation for possible practical test. PowerMill software proved to be not very suitable for this kind of machining application, mainly because of high amount of time consumed during the whole process. So the original idea of replacing classical on-line programming with this software is not advised.

Design of a Robotic Cell for Weding Application
Rolinc, Lukáš ; Kubela, Tomáš (referee) ; Pochylý, Aleš (advisor)
The diploma thesis deals with the design of a workplace with robots designed for spot welding of wire reinforcement of the car seat. After analyzing and description of the given task, the workplace concept is chosen based on the input parameters. Subsequently, sub-systems of the production cell are designed and selected for this concept. For example the design of clamping fixtures, rotary table, input and output storage magazines or the selection of welding guns and robots are solved. The workplace is designed to ensure operator safety and protection. The production cycle of the designed workplace is simulated in Siemens Process Simulate to verify functionality and required productivity of the production line. Technical and economic evaluation of the proposed solution is also included in this diploma thesis.
