3차원 탄소성 유한요소해석과 쾌속생산방식을 이용한 시작 금형 개발에 관한 연구

The objective of this research works is to propose a rapid development methodology of try-out tools for sheet metal forming using the 3D elasto-plastic finite element analysis and rapid manufacturing technology. The proposed technology is applied to the development of deep drawing tools with a drain shape. The final surface of tools is obtained from the evaluation of the formability using the CAE. In order to manufacture the physical prototypeof tools for try-out forming, several fabrication experiments are carried out for three types of rapid tool manufacturing technology. Through the fabrication experiments, the acceptable rapid manufacturing technologies of deep drawing tools with a small size have been proposed.
