Forging with optimal back-pressure profile using sequential approximate optimization
Nihon Kikai Gakkai ronbunshu, 2014 This paper proposes a method for determining optimal back-pressure profile in forging using a sequential approximate optimization (SAO). In forging, it is important to minimize an unfilled area for improving the product quality. To achieve this objective,
