Abstract：

Numerical simulation technology has been widely applied to study in the springback forecast, much implicit knowledge in a lot of analysis results lacks an effective method to be analyzed and concluded in deeply, so a lot of knowledge is wasted. Combined with variable BHF, springback of aluminum alloy U-shaped workpiece was extensivly studied. Knowledge discovery technology based on a rough set was proposed, the validity of this method was proved through specific calculation, hidden knowledge of stamping springback was gained to form a lot of experimental data.
