A Finite Element simulation of the hot forging

Hot forging process currently requires a succession of preforming operations to target the final form.The shape of each preform is based on how the workpiece material must be distributed for most effective forging in the next impression.The number of preform impressions is difficult to determine for forgings characterized by irregular shape and a length somewhat greater than the other A Finite Element simulation of the hot forging KeywordsForging simulation,virtual manufacturing,hot forging,finite element.Hot forging process currently requires a succession of preforming operations to target the final form.The shape of each preform is based on how the workpiece material must be distributed for most effective forging Expert system for hot forging design SemanticDOI 10.1016/S0924-0136(98)00182-4 Corpus ID 16099226.Expert system for hot forging design @article{Caporalli1998ExpertSF,title={Expert system for hot forging design},author={{\^A}ngelo Caporalli and Luciano Antonio Gileno and S.Button},journal={Journal of Materials Processing Technology},year={1998},volume={8081},pages={131-135} }
