To compensate for taper a rotatable, forming tool is moved inwardly toward the longitudinal axis of the airfoil as the tool is moved through a working stroke along an edge of the airfoil. To compensate for the bowed side surfaces, the forming tool is pivoted in such a manner as to maintain its axis of rotation perpendicular to an arcuately curved edge being shaped by the tool.
