ABSTRACT:
A system and method are described for ballizing and measuring a workpiece bore hole. In one embodiment, a ballizing unit having a distal end removably coupled to a ballizing member moves the ballizing member from a first position within the bore hole to a second position. A metrology unit having a distal end removably coupled to the ballizing member moves the ballizing member from the second position back to the first position. A sensor detects a force exerted on the ballizing member by the workpiece at a third position, which is located between the first and second positions.
