![]() ![]() Modern components increasingly present challenging shapes and geometries for inspection. In civil aerospace manufacturing, the increasing deployment of composite materials demands a high integrity and traceability of NDT measurements. ![]() The path error relative to a raster-scan tool-path, suitable for ultrasonic phased array inspection, has been measured to be within ± 2mm over the 1.6 m 2 area of the component surface. The path trajectory generation for a large, curved carbon-fiber-reinforced polymer (CFRP) aerofoil component has been proven and is presented. Ultrasonic and experimental data has been collected for the validation of the inspection technique. Crucially the approach provides a pathway for a conditional programming approach and the capability for multiple robot control (a significant limitation in many current off-line programming applications). The developed software maintains a high level approach to the robot programming, in order to ease the programming complexity for an NDT inspection operator. Using a flexible approach in MATLAB, the authors have developed a high level custom toolbox that utilizes external control of an industrial 6 axis manipulator to achieve complex path planning and provide synchronization of the employed ultrasonic phase array inspection system. The key novelty of the approach is through the accommodation of flexible robotic trajectory planning, coordinated with the NDT data acquisition. A new system for robot deployed ultrasonic inspection of composite aerospace components is presented. The prevalence of complex curved surfaces in the industry provides significant motivation for the use of 6 axis robots for deployment of NDT probes in these inspections. The requirement to increase inspection speeds for non-destructive testing (NDT) of composite aerospace parts is common to many manufacturers.
