Abstract: A system and method for detecting a defective part and the type of defect formed during stamping operations. The system and method will not only detect the defect but also the nature of the defect and the time at which the defect occurred during stamping operations. Such information is useful not only in quality control but also in isolating a problem which may exist in stamping operations and thus eliminating time for isolating such problems and correcting them. The system and method uses a profile of a properly stamped part to detect a defect, and the root cause of the defect.

Abstract: A method of assessing the quality of metal parts, for example through detection of defects in a metal part induced by processing the metal part, comprises acquiring a thermal image of the metal part after processing the metal part, determining a difference image by comparing the thermal image to a reference image, the difference image being related to temperature differences between temperature data represented by the thermal image and by the reference image, and determining a gradient image using the difference image, the gradient image representing temperature difference gradients within the difference image. An example apparatus comprises a camera, such as a thermal camera, an image processor, and an output device such as a display.
