Earing Reduction by Varying Blank Holding Force in Deep Drawing with Deep Neural Network
In the present study, we propose a novel method of varying blank holding force (BHF) with the segmental blank holder and investigated its influence on the earing reduction in the circular deep drawing process of an aluminum alloy sheet.
