Abstract: The present invention relates to a system and method for detecting the efficacy of machined parts, and particularly to an automated system and method that detects whether tooling features (e.g., holes) are properly formed and aligned in work pieces during the machine tooling process. In one embodiment the system and method includes at least one roller that engages an associated work piece and is capable of applying a rotational force to the work piece, a source of electromagnetic radiation emits electromagnetic radiation through at least one feature of the associated work piece, and a detector for detecting a characteristic associated electromagnetic radiation with the at least one feature of the electromagnetic radiation when the rotational force is applied. The detected characteristic of the electromagnetic radiation is used to determine whether the work piece has been properly tooled (or machined) or contains a defect.
