A Comparative Analysis between 2D and 3D Modeling in the Piercing Process of Lead Frame and Experimental Study
초록
Piercing or blanking process is widely used to manufacture most of lead frame parts, but it is difficult to analyze the real process by the actual shape through progressive dies. In this paper several stages in progressive punching are modeled by 2D and 3D configurations using
