[Larger slab][Optimal Design]Open-die forging of larger slab

An open-die forging process of larger slab was simulated to conduct process design optimization to increase product quality as well as yield rate. Fig. shows a typical example, which consists of about 300 blows. The simulation was conducted in semi-automatic way, i.e., user-intervention is made only when material adjustment is needed, for example, rotating and initializing it.
