“Jesse Garant Metrology Center has been performing CT scans of cast aluminum housings for two of our helicopter fuel control applications for the past 5 years.  These scans have been used to check for the presence of local thin walls within the housings.  In one case, the scans were performed on the raw castings.  Those identified with thin walls were scrapped prior to any machining operations being performed, thus saving the investment of machining costs into housings that ultimately would be scrapped.  In the other case, the suspect walls were next to critical machined features, requiring the scans to be completed post-machining.  In this case while we were unable to prevent the investment of machining costs into the housings, the scanning prevented defective product from being delivered to the customer.”
