摘要： A method and system are provided for non-contact evaluation of a machined surface of a cast-metal part, including a vision-based porosity inspection station. A digital image of the machined surface is acquired, oriented and scaled to an XY coordinate system, filtered, and inverted. A second image is generated with known design surface features eliminated. Each pixel of the inverted digital image is XOR-compared with a corresponding pixel of the second image. Identified common surface features common to both images is analyzed statistically for conformance to a threshold. A defect is identified as any identified surface feature common to both images which exceeds the threshold. The system moves the part for further processing if a statistical analysis of defects indicates an acceptable component, and alternatively, removes the part from further processing if the analysis indicates a flawed component.

摘要： A pair of form keys and a method for forming reverse drafts in foam parts are disclosed. A male form key is reciprocally mounted in a first mold half in a retracted position. A female form key is rotatably mounted in a second mold half in a neutral position. The first mold half includes a first drive pin that when engaged, moves the male form key into engagement with a foam sheet to form an undercut as the first and second mold halves are closed. The first mold half also includes a second drive pin that engages the female form key as the first and second mold halves close rotating the female form key into engagement with the foam sheet and the male form key. After closure of the mold and the product is formed, the mold is opened. As this occurs, the drive pins are disengaged and the male form key retracts and the female form key rotates to their neutral positions. The formed product may then be stripped from the mold while maintaining the reverse draft or undercut.
摘要翻译：公开了一种形式键和在泡沫部件中形成反向牵引的方法。阳形成钥匙在缩回位置的第一半模中相互安装。阴形密钥钥匙可旋转地安装在中间位置的第二半模中。第一模具半部包括第一驱动销，当第一和第二半模封闭时，第一驱动销接合时，移动凸形键与泡沫板接合，形成底切。第一半模具还包括与第一和第二半模相接合的第二驱动销，该第二和第二半模闭合使阴形密钥键旋转与泡沫片和阳形密钥卡合。在模具闭合并形成产品之后，打开模具。当这种情况发生时，驱动销被分离并且凸形键缩回并且凸形键旋转到它们的中立位置。然后可以在保持反向牵伸或底切的同时从模具剥离成形的产品。
