Springback Prediction and Compensation

 

 Springback Prediction

 

The Process

New high strength steel & aluminium alloys, used to reduce weight in vehicle body structures, are subject to much higher levels of springback than conventional deep drawing steels. This can prolong tooling buy-off whilst acceptable dimensional integrity of components is achieved. This project has established a validated Finite Element method to accurately predict springback and propose modifications to the tooling design to reduce costs without reducing part quality.

 

The Benefits

Implementation will:

- Reduce time/cost to physically prove-out press tools through optimised component design and process planning

- Reduced material requirement

- Facilitate tailored and potentially tighter tolerances on pressed parts, leading to better dimensional accuracy of assemblies
