Zdokonalení technologie výroby součásti typu příruba / Improvement of manufacturing technology of flange

Dvořák, Jakub January 2019 (has links)
This diploma thesis focuses on improvement of the existing technology of the flange part in cooperation with the company Znojemské strojírny, s r.o. The theoretical part describes the technologies used in machining of the component. Subsequently, cutting materials and aluminum alloys are dealt with. A detailed analysis of the existing technology is performed in the practical part of the thesis followed by rationalization of the production process, which was carried out with respect to time and financial savings. A new technological procedure is developed after the improvement of the current production process. Finally, a technical-economic evaluation of the design improvement process is carried out.

Simulační studie robotické linky pro obsluhu obráběcího stroje pro velkosériovou výrobu / A simulation study of a robotic cell for production machine operation for large-scale production

Šváček, Jiří January 2020 (has links)
The thesis deals with design of robotic cell for operation with CNC machine. When CNC machine is machining, inactive robot is used for deburring specific edges on the workpiece with help of pneumatic spindles. Thesis include design of end-effectors for handling and deburring operations, design and placement of individual parts of robotic cell. Part of the thesis deals with safety of the cell. Next part of thesis is focus on finding out cycle time of the robot. Robot have to manage cooperate with CNC machine and deburr edges in time. Cycle time is find out at simulation study in software called Tecnomatix Process Simulate. On the end of thesis is technical-economics evaluation
