A Simplified Prediction Approach For Localized Unstable Springback Due To Oil Canning Effect

Abstract

Dimensional precision is a major key factor for robust automated production. Springback is one of the most important effect to reduce part geometry level. Also unpredictable springback such as oil canning effect which has eliminates compensation possibilities to ensure part geometry. In this paper the prediction of oil canning effect in forming simulations is presented. Simple prediction approach with clamping forces have been investigated and compared with real measurements.
