Abstract: A die of a stamping press includes: an upper portion including one or more first features and first bores that extend partially through the upper portion; magnets disposed within the first bores, respectively; a lower portion including one or more second features that are complementary to the first features and second bores at locations, respectively, that extend partially through the lower portion; and magnetic flux sensors that are disposed within the second bores, respectively, and that are adjacent to the magnets, respectively, and that are configured to measure distances between the upper and lower portions at the locations.

Abstract: A die of a stamping press is described and includes: an upper portion including one or more first features; a lower portion including one or more second features that are complementary to the first features and apertures at locations, respectively, that extend through the lower portion; and optical sensors that are disposed within the apertures, respectively, of the lower portion and that are configured to measure directions of movement and distances of movement inward of outer edges of a substrate at the locations, respectively, during stamping of the substrate.

Abstract: The present document describes methods and systems for the automatic inspection of material quality. A set of lights with a geometric pattern is cast on a material to be analyzed. Depending on the material being inspected, same may act as a mirror and the reflected image is captured by a capture device, or the light passes through the material being inspected and the image is captured by a capture device. Defects in the material can be detected by the distortion caused by same in the pattern of the reflected image or passing through. Finally, software is used to identify and locate these distortions, and consequently the defects in the material. This classification of defects is carried out using artificial intelligence techniques.
