and why should the defect be at one area on the disk rather than just anywhere ? unless of course it's a machining process defect?
Because the defect is contained in the billet. the billet is sliced into what will be multiple disks after forging. The forging process then moves the defect into a particular location of the forged disk. It is not a haphazard event. Fact is, if you were to locate the defect in the billet slice, a computer program can predict after forging where the defect will wind up. Something new in technology comes along everyday, eh?
