[0002] In modern industrial production, sheet metal forming quality inspection is a critical step in ensuring product quality and production efficiency. Sheet metal parts are widely used in a variety of fields, including automotive manufacturing, mechanical processing, electronic equipment housings, and architectural decoration. Their forming quality directly affects the product's appearance, performance, and service life. However, traditional sheet metal forming quality inspection methods have several limitations, limiting their application in efficient production and precise inspection.
