Closed-loop Sheet Metal Forming Using Dieless Forming Apparatus
무금형 성형장치를 이용한 폐루프 판재성형
Abstract
A dieless forming system which consists of hydraulic punch elements and elastomer/fluid pads, was developed for sheet metal forming. 2-D curved surface forming was carried out using open-loop, closed-loop, and repeated forming method. Closed-loop exhibited higher decision than open-loop forming. Repeated forming also showed reduced spring back and possibility of high precision.
