    Automatic visual inspection system for cold forgings

    Screen announces an automated visual inspection system for cold-forged rotation parts with its IM-5100 solution. The new development on show at EMO Hannover 2017 adopts the company's optical system technology and a high-precision inspection algorithm that reportedly enables the detection of a defect the size of several tenths of a micrometer within 7 seconds.

    The IM-5100 can conduct a high-precision inspection that reliably detects micro-defects with a cycle time of 7 seconds.

    Screen points out that the performance of the IM-5100 has been demonstrated in an internal company study. As is explained, the system also removes irregularities on the surface of cold-forged parts created by lubricants or rust prevention treatment and controls excessive detections. Moreover, through the positioning of multiple optical sensors, it is said to be able to inspect the interior of the outer race as the coupling part of an obscured constant-velocity joint component. The solution thus contributes to productivity and quality improvement for cold-forged parts that require special safety. As a result, the Japanese developers maintain, the inspection system solves the specific problems of the appearance on cold-forged parts that cannot be mastered by conventional cameras and software. These problematic aspects include the difficulty in observing the bottom and shafts of workpieces, cases where the form comparison cannot be made due to large tolerances, and situations where the lighting and images are uneven. The exhibitors say they accomplish the automated visual inspection by utilizing their unique All-Angle Multi-Shot system together with image comparison software. The special combination of line sensors and lighting is claimed to enable the detection of defects on gear flanks and the inside areas of cup-form parts that are not easily visible.
