Patent ID: 8366515

Claim:
A method of finish grinding an airfoil, the method comprising the steps of: driving a first continuous abrasive belt over an area of a suction side of the airfoil, wherein the first continuous abrasive belt is driven along a first form transfer tool having a contour corresponding to a desired final contour of the suction side of the airfoil; and driving a second continuous abrasive belt over an area of a pressure side of the airfoil concurrently with driving the first continuous abrasive belt over the suction side of the airfoil, wherein the second continuous abrasive belt is driven along a second form transfer tool having a contour corresponding to a desired final contour of pressure side of the airfoil, wherein the first form tool and the second form tool comprise a fixed contoured surface having a length extending in a direction in which the first and second continuous abrasive belts are driven that is greater than a width of the airfoil.
