An Application of Optimal Blank Design by Sensitivity Analysis to Stampings of General Shaped parts

민감도를 이용한 최적블랭크 설계법의 CAD 형식으로 표현된 금형에의 적용

The optimal blank design method by sensitivity analysis has been applied to the formings of oil-pan, tailored blank and front panel have been chosen as the examples. Die shape is prepared by a commercial CAD system. Excellent results has been obtained between the numerical results and the target contour shapes. Through the investigation, the proposed systematic method of optimal blank design is found to be effective in the practical forming processes.
