Frictional and Forming Behavior of Zinc-Coated Steel Sheets 960818

The application of coated steel sheets is gaining importance in the automotive industry. To determine the friction and the forming behavior, tests were carried out to investigate the influence of different lubricants and tool materials. A segmented draw die was developed for measuring friction and punch forces during the deep drawing process using segments made out of different tool materials. The forming behavior was investigated using a draw part of the size of an typical automotive body part. The change of surface topography parameters due to the forming process was determined with a laser topography device.
