Abstract:

A method and device is provided for measuring springback of a vehicle panel within a deformation press. This avoids the need for removing the panel from the press and fabricating a dedicated measuring fixture. A trim die in the deformation press is retrofit to perform an additional function, namely securing a deformed panel in a position such that a measurement of the panel can be made. The trim die is retrofit by modifying existing apertures and adding additional aperture(s) in required positions. In the process, after bending the panel into the press and, using the trim die, undesired material is trimmed from the deformed panel. The panel is raised and at least three fixture posts are placed in apertures in the trim die. The panel rests on the posts with one post securing the panel in either one, two or three directions. The panel is then scanned or otherwise measured to determine springback in the panel.
