Patent ID: 7568370

Claim:
A system for ballizing, and measuring a diameter of, a bore hole of a workpiece, the system comprising: a ballizing unit having a ballizing pusher with a distal end capable of being removably coupled to a ballizing member, the ballizing unit configured to move the ballizing member along an axis from a first position within the bore hole to a second position within the bore hole; a metrology unit having a metrology pusher with a distal end capable of being removably coupled to the ballizing member, the metrology unit configured to move the ballizing member along the axis from the second position to the first position; and a sensor coupled to the metrology pusher and configured to detect, as the metrology unit moves the ballizing member from the second position to the first position, a force exerted on the ballizing member by the workpiece at a third position within the bore hole, the third position being disposed between the second position and the first position.
