In forging processes, it is necessary to prevent damage to dies caused by high forging loads and to avoid the underfilling of billets within the dies. Therefore, it is essential to suppress forging loads while meeting the dimensional requirements, and it is important to optimize both the billet and die shapes. However, as the shapes of forged products become increasingly complex, determining the shapes of billets and dies becomes more challenging and is often resolved through trial and error. In this study, computer-aided engineering (CAE) integrated with sequential approximate optimization is used to simultaneously design the optimal billet and die shapes. As a result, the optimal conditions are obtained to suppress the maximum forging load and meet the target size of the forged product.
