Abstract

Visual inspection of casting surfaces is a critical processing step in the metalcasting process. Measurement error can be significant, causing overprocessing or poor quality received by the customer. Many factors affect the human operator's ability to effectively inspect castings. Cognitive ability is one such factor, which can be identified through a simple test. Rastering training was shown to improve the percentage of casting surface which gets inspected. Discrimination between acceptable and unacceptable surfaces continues to be problematic.
