Reducing springback, especially when forming advanced high-strength steels (AHSS), is a major challenge in sheet metal forming. The article “Reducing springback in hat-shape bending with variable BHF using a servo-hydraulic cushion,” published in the March/April 2018 issue of STAMPING...

Springback in AHSS and high-strength aluminum alloys can cause geometric and dimensional inaccuracies in the formed part. Researchers at the Center for Precision Forming at The Ohio State University, in cooperation with Hyson Metal Forming Solutions, Brecksville, Ohio, conducted a study of a relatively simple, 2-D hat-shape bending operation.
