Due to an increasing level of function integration mechanical components have increasing number of intersecting holes. Until today, the resulting burrs at the intersecting contour can¿t be reliable removed by automatic manufacturing processes. Particularly at security relevant parts a peel of these burrs needs to be prevented. So in the industry at a wide range of mechanical components a very costly and time-consuming manual deburring process is used. The goal of this research project is the development of a deburring process based on industrial robots for the deburring of intersecting holes. The procedure will be demonstrated at typical holes which can be found in hydraulic valves. The solution includes an adaptable automation concept which can record the position of each hole and thus enables the calculation of the intersection geometry. Thereby the positioning inaccuracy of the robot and tolerances of the holes can be taken into account. For the deburring different tools will be tested. The generation of corresponding tool paths requires different software systems (e.g. a CAD/CAM system and a robot specific postprocessor). Therefore another goal of the project is the integration of both functionalities in one simulation environment. By using special optimization algorithms the order in which way the holes are machined additional optimization potential will be exploited.
