Summary:

A three-dimensional surface profilometer has been used to examine the surface morphology in various regions of stamped automotive steel parts. This analysis provides insight into the nature of the surface morphology development during stamping. For this work, four stamped zinc-coated sheet steel sections were considered. Each of the sections was examined with the 3-D surface profilometer in a variety of regions suspected to show different surface morphology due to differences in forming. Upon analysis of the surface height frequency histograms, different modes of deformation on the part surface were identified and categorized. Three modes of surface deformation were observed - "simple pressing", "pressing with small scale sliding and bending" and "pressing with gross sliding, stretching and bending". Each mode had a distinctive set of characteristics in the frequency height histograms. These modes were observed in both galvannealed steel sheet and hot-dipped galvanized steel sheet. From the surface morphology development, frictional effects can be hypothesized
