Method and device for at least sections, preferably complete determination of the outer and inner geometry of a component having at least one cavity

摘要

The invention relates to a method for determining the outer and inner geometry of a component (1) having at least one cavity, in which a component (1) to be measured is provided with at least one cavity (S1), the external geometry of the component (1) is determined by performing a 3D scan (S2), - The wall thickness is determined by ultrasound of at least a portion of the component (1) (S4), - In particular of at least a portion of the component (1) the inner and outer component geometry is determined by X-ray computed tomography (S5), and - The data obtained by the 3D scan and the ultrasonic wall thickness measurement and in particular by the X-ray computed tomography are merged, wherein from the data of the 3D scan on the outer geometry and the data of the ultrasonic wall thickness measurement, the inner geometry of the component (1) in the reconstructing at least one ultrasound-measured portion (S6). Moreover, the invention relates to a device for determining the outer and inner geometry of a component (1).
