Summary:

Springback is a formidable problem in many of today's sheet metal stampings. Correction for springback is based on "rules of thumb" and experience. Today's wide range of materials and forming processes have led to increasing trouble when attempting to compensate for springback during the design stage. Materials such as high strength steel and aluminum, with their increased tendency for springback, are now used for a wide range of autobody components.This springback study utilized a test channel designed specifically to study the effects of springback. The die is capable of both crash mode and draw mode forming operations. The study compared different materials, sheet thickness, and blank rolling direction orientation. Three levels of lubrication (dry, flooded, and barrier) were evaluated. The measurement of springback for these experimental panels provides a solid basis for correlation with springback simulation in the future
