Abstract: Blank holder force (BHF) is an important measure to control the sheet metal forming.BHF is identified quickly using artificial neural network (ANN) on the basis of itsanalytical description. And critical rupture and wrinkle BHF curves are given. Aclose-loop control system is established to finish the forming process.
