Robust automated deburring

This finishing Master Thesis Work is a part of a new development project “Robust Automated Deburring” for precision deburring of compressor- and turbine discs. The purposes for the project is together with suitable partners demonstrate an automated system together with sensors for deburring not well-positioned surfaces. The edge break is now done partly manual because of robots limitation in achieving the required quality and accuracy. A typical edge breaking requirement is 0, 38-0, 76 mm on discs. Aero engine components are often exposed to high stress levels and vibrations during operations. Burrs and sharp edges on these components can lead to edge cracking and component failure. So therefore removal of burrs and creating rounded edges is necessary. Sensors can be used as a helping tool managing the problem with removing burrs that you with certainty not can define the size of, at the same time edge position varying. General there are four problems VAC wish to solve: 1. Robots have bad path following. 2. The position on the edges deviates from component to component. 3. Size of the burrs (root thickness) is varying. 4. Work hardening of material and burrs is different from component to component. This project demands an overall solution for a system that can work integrated together and within VAC tolerances. Example for sensor systems: laser triangulation, vision system, force control or compliance in combination with some kind of sensor.Validerat; 20101217 (root
