Development of Multi-point Digital Forming Technology for Freeform Surface

Abstract

Basic principle of multi-point forming technology was introduced.Research situation of multi-point forming in Japan,USA and South Korea was described.Researchers in Japan developed several multi-point forming experimental equipments in 1959-1980,but 3-D surface forming question was not solved.Researchers in USA developed multi-point stretching equipment in 1999.Researchers in South Korea developed multi-point elastic forming equipment in 1990s.Research situation which including forming theory,forming equipment and forming process was described.Development trend of multi-point forming was pointed out,large-scale forming,precision forming and continuous forming being the important development direction.
