Claim:
1. A method comprising: identifying an engine-run tip position for an airfoil having a tip section and a root section, the engine-run tip position having a displacement and a rotation with respect to an original tip position, wherein the original tip position is defined with respect to the root section before engine running; forming an airfoil tip on the tip section of the airfoil; defining a machining datum adjacent the airfoil tip, wherein the machining datum is spaced from the root section; deforming the airfoil to locate the airfoil tip in the original tip position, independent of a position of the root section; and machining the airfoil tip of the deformed airfoil along a machining path to restore a tip profile on the engine-run airfoil, wherein the machining path is defined with respect to the machining datum adjacent the tip section and is independent of the displacement and rotation of the engine-run tip position, and independent of the position of the root section.
