Friction Behavior under Different Forming Speed for Sheet Metal Forming

Abstract:

In sheet metal forming, the friction between tooling and workpiece is an important factor which affects not only the quality of products but also the service life of tooling. In order to consider the effects of friction accurately for the optimization of stamping process and simulation, the friction behavior under different forming speed was investigated via tensile strip experiments. A 10000N servo-press which forming speed is ranged from 0.1mm/s to 200mm/s was used to collect the experiment data. Based on these data, the law of friction between tooling and workpiece was derived, it will be very useful to help set up the displacement-force and forming speed curve for the optimization of stamping process when a servo-press is employed.
