Zone for Local Support The center point of the supporting forming tool, T C P 2 , needs to be along the vector, V L , from the center point of the master forming tool, T C P 1 , to the point of contact, Pc. T C P 2 is translated from T C P 1 along V L with a magnitude, M v , of: Mv = r1 + t + r2 r 1 = radius of master forming tool t = thickness of formed sheet r 2 = radius of supporting forming tool This allows the supporting forming tool to be in a variety of positions and orientations. The shifting angle, γ m a x , is bound between 0 o , when the tools are directly opposite eachother, and N α , the angle normal to the wall angle, α . 38
