O5M-498 CT INSPECTION OF CASTINGS WITH IMPROVED CALIBRATION

Copyright © 2004 SAE International Maintaining the high quality level of today's cars requires inspection by a variety of non-destructive testing methods. Specialized techniques are needed for highly stressed parts such as cast aluminum cylinder heads. Computerized Tomography (CT) is one of the best testing methods for checking complex areas such as combustion chambers, inlet/exhaust runners, and coolant passages. CT inspection simultaneously detects in-homogeneities, pores, shrinkages, and cracks while acquiring complete 3D dimension information on all internal and external surfaces. This adaptation of well-proven medical technology is now maturing to applications in the industrial environment and achievin
