Patent abstract

An apparatus for measuring wall thicknesses of objects, includes a coordinate measuring machine that has a probe holder and an object support. The coordinate measuring machine is configured to provide relative movement between the probe holder and the object support in three dimensions. The apparatus also includes an ultrasonic test probe which is held by the probe holder. The coordinate measuring machine brings the transducer of the ultrasonic test probe into contact with a position on a surface of an object at the object support so that the probe can measure an object wall thickness at the probe contact position.
