  • Patent number: 7411150
    Abstract: A composite component (1), such as a turbine airfoil, includes a conductive portion (2), and a non-conductive portion (5), such as a thermal barrier coating or a wear protection coating, or both. In machining the component, a laser machining step is applied for machining the non-conductive portion, and an electro-machining step is applied for machining the conductive portion. The laser machining step is performed by applying preferably a high-frequency pulsed laser. The focussed laser beam working diameter (DL) is essentially smaller than the size of the contour (16) to be machined. The contour is scanned by the laser beam (9) along a pre-defined trace (17) thus literally inscribing the desired contour into the workpiece.
