Aero-engine disc components such as bearing rings, fan and compressor discs are typically inspected at different stage of manufacturing from their pre-formed to final machined shape. Engine bearing are among components that are inspected at different manufacturing stage, from dimensional controls to the detection of the tiniest surface flaws on rolling surfaces (bearing raceways). Complementary NDT technologies such as ultrasonic, liquid penetrant and eddy current testing are used for flaw detection. One th
