Springback Analysis in the Anisotropic Sheet Metal Forming Process with Axisymmetric Tools

이방성 금속판재 성형공정에서 블랭크 가압력에 따른 스프링백 해석

The deterioration of dimensional accuracy, caused by springback, is one of problems to always occur in sheet metal forming processes. As the demand for lighter and stronger metals increases, the development of improved forming processes settling the springback problem becomes more important. In this work, springback phenomena are investigated which occur in the press forming process with the anisotropic sheet metal and axisymmetric tools. The improvement possibility of dimensional accuracies, mainly, flatness, will be examined by applying blank holding forces as a method of springback control.
