In order to meet the requirements of rising flexibility and an automated material inspection in a small batch production environment, an automatically changeable ultrasound sensor tool for milling machines has been developed. This system enables an automated ultrasonic inspection of varying parts to be carried out directly on a machining center and visualizes hidden geometries and material imperfections three-dimensionally. The sensor tool is based on commercialized ultrasonic squirter-probes, which are able to use the cooling lubricant for sound coupling. During the measurement recordings, the milling machine's axes move the sensor numerical-controlled across the workpiece. By this means, automated material inspection tasks can be performed very cost-effectively without setting up separate testing facilities. 4- or 5-axes kinematics capacitates the system to check even very complex-shaped parts.
