Abstract：

The formability of FVS0812 sheet is bad and the forming of FVS0812 sphere-shaped part is difficult.Based on experiments,a novel forming technology was presented,named as "packed-layer drawing".A low relative-thickness coefficient sphere-shaped part was drawn successfully by "packed-layer drawing".Both wrinkling and fracturing could be effectively prevented by the technology.The formability of metal-sheet can be improved because the deformation of metal-sheet scattered uniformly."Packed-layer drawing" is fit for the drawing of low plastic metal-sheet.
