Aiming at springback errors, a closed-loop accuracy control system for complex 3D sheet metal stamping was constructed based on RP/RT/RE. The computational formula of DMA(dies-modification algorithm) was derived in the prerequisite of small springback deformation and steady-going stamping process parameters. The algorithm based on theory of linear closed-loop control system ,space Fourier transform , transfer function in frequency domain and die experimental iteration. DMA is used for the first time in the fabricating of complex 3D sheet metal stamping dies.
