To make vane airfoils for an axial flow compressor metal strip is first contour rolled to a cross section comprised of two opposing airfoils separated by a center rib, where one of the faces of the strip is kept planar. The rib is used to guide the strip into dies where it is notched and slotted to define individual airfoils. Next, die stamping makes concave the planar surface of each airfoil. |
