In order to improve the quantitative analysis accuracy of stamping mould wear,a numerical simulation method of stamping mould wear based on rolling scheduling is proposed.The dynamic profile sampling method is used to collect the wear value of stamping die,and the rolling scheduling after numerical sampling of mould wear is carried out by combining multi-sensor fusion sampling method.The numerical information fusion and feature extraction model of mould wear are established,the spectral characteristic quantity of wear data of stamping mould is extracted,and the numerical fitting and adaptive scheduling of mould wear are carried out by means of spectral analysis.The rolling scheduling model of numerical simulation of stamping mould wear is established,and the rolling scheduling motion analysis model of stamping mould wear is established from the kinematic point of view.The adaptive prediction method of workpiece surface morphology is used to realize the numerical simulation of stamping mould wear.The simulation results show that the numerical simulation of stamping mould wear using this method has high accuracy and good fitting,and improves the ability of numerical simulation and parameter estimation of stamping mould wear.
