A method of machining an airfoil includes the steps of providing first and second cutting tools (40,140) respectively having first and second cutting contours (42;142) that are different than one another. A blank (19) is cut with the first cutting tool (40) to provide a first airfoil surface (54) on a first blade (24b). The blank (19) is cut with the second cutting tool (140) to provide a second airfoil surface (52) on a second blade (24a). An airfoil is produced having the first and second blades (24a,24b). A cutting tool (40) for machining the airfoil includes a shank (44). A cutting surface adjoins the shank (44) and provides a cutting contour (48) corresponding to an airfoil surface. The cutting surface extends along a cutting length axially from a nose to near a cutting boundary. The cutting length is configured to be greater than the blade length. |
