Reversing factor springback compensation method based on reverse engineering technology

To reduce the compensated times of die surface leaded by springback, a reversing factor compensation method based on one-step molding surface geometry correction was proposed. A stamping digital model was obtained by reverse engineering, and the stamping was regarded as a theoretical profile to calculate the simulation of springback amount. The real compensation amount was obtained by taking the deviation of mold surface and the stamping, thus the compensation factor was calculated. Under the assumption that compensation factors kept unchanged with stamping small deformation, simulation parameters and stamping process were unchanged, the springback stimulation for real ideal parts was made to calculate die surfaces by introducing compensation factors. Experiment results showed that the springback could be controlled and the compensation efficiency was greatly improved with one-step mold surface compensation. ©, 2015, CIMS. All right reserved.
