The quality of precision casting products requires accurate quality inspection because quality errors occur due to micrometer units. In the casting process, quality inspection is carried out through warehousing inspection, dimensional inspection, hardness inspection, and tissue inspection.
At this time, the surface is verified for appearance defects such as stains, foreign substances, and scratches, and the surface inspection is performed with a vision system and a visual inspection. Recently, machine vision technology based on artificial intelligence plays a very important role in detecting defects and defects of parts in manufacturing production lines. In this regard, vision systems are being studied in various fields by combining image processing technology and artificial intelligence.
