Surface defects can develop on automotive exterior panels after drawing and ﬂanging steps, during springback and may alter signiﬁcantly the vehicle quality. These defects are characterized by a depth below 0.5 mm and are then diﬃcult to detect or predict numerically. This study focuses on a L-shaped part designed on purpose to reproduce at a small scale surface defects that occur after ﬂanging. Dimensions of these defects are measured from proﬁles obtained with a tridimensional measuring machine. The investigation of the inﬂuence of the ﬂanging height and ﬂanging speed shows than neither of these parameters have impact on the surface defect . The numerical simulation of the ﬂanging process predict the surface defect but with a lower depth than the experimental defect.
