APPLICATION OF PHYSICAL MODELING, FEM AND KNOWLEDGE-BASED PROCESS PLANNING PROGRAM TO FORGING PROCESS DESIGN

In order to develop the forging process for a cup-shaped product, thre e methods for process modeling and design have been applied. As an exp erimental approach, physical modeling with plasticine has been perform ed. A commercial FEM code DEFORM and a knowledge-based process plannin g program have also been used as computational methods. Partial forgin g technique has been proposed to forge a large forging with a capacity -limited machine and verified with the above process modeling and desi gn methods. It has been found that the proposed forging process is fea sible in the modelings. The actual forging of this product has been su ccessfully performed proving that these approaches are reliable in dev eloping the forging processes with efficiency and low cost.
