Automated Repair of Fiber Composite Structures based on 3D-Scanning and Robotized Milling

摘要

The repair of fiber composite structures from airplanes and helicopters is a complex and expensive process. The aim of the project Rapid Repair is the development of an integrated process chain for a fast, automated and reproducible repair of high performance fiber composite structures. With the help of modern optical fringe projection technology the exterior shell of an aircraft can be scanned in 3D. For this, the company GOM has optimized the digitizing software and hardware for capturing materials which are typical in aircraft construction. After the scan data has been transformed into the coordinate system of the robot a software developed by iSAM AG jointly with the IFB, Stuttgart automatically generates the robot program not only for the scarfing itself but also for patch and tool generation.
