Abstract

This paper proposed a mould modification algorithm based on improved Fast Fourier Transform. The wavelet transform and Fourier transform are used to solve the shape transfer function of the springback closed-loop control system. Through the shape transfer function to predict the mould surface shape corresponding to the stamping parts shape in the same process conditions, so as to achieve the purpose of correcting the mould surface to compensate springback error. Finally, this paper verified the effectiveness of mould surface springback correction algorithm based on multi-curvature stamping experiment.
