Abstract

Two kinds of experimental dies containing class "A" surface feature of auto body outer panel are designed and manufactured in order to emerge the surface wrinkle of auto body panel. By doing stamping experiment in the dies, the wrinkling phenomenon is observed. At the same time, numerical simulation based on an independently developed commercial CAE software KMAS/UFT of sheet metal forming is carried out. Comparison between experimental and simulated results is done which shows good consistence. And then a Universal Formability Theory called UFT is introduced to optimize the adjustment amount of metal flow and the stamping dies. Some suggestions are given by investigating the adjustment amount and modification of the stamping die.
