A method of removing material from an airfoil includes engaging a root of the airfoil within a root-securing fixture, engaging a tip of the airfoil within a tip-securing fixture, and removing material from the airfoil. The method further includes disengaging the tip of the airfoil from the tip-securing fixture to allow movement of the tip from a clamped state position to a free-state position. The method further includes reengaging the tip of the airfoil within the tip-securing fixture in the free-state position, and removing additional material from the airfoil. 1. A method of removing material from an airfoil , the method comprising:engaging a root of the airfoil within a root-securing fixture;engaging a tip of the airfoil within a tip-securing fixture;removing material from the airfoil;disengaging the tip of the airfoil from the tip-securing fixture to allow movement of the tip from a clamped state position to a free-state position;reengaging the tip of the airfoil within the tip-securing fixture in the free-state position; andremoving additional material from the airfoil.2. The method of claim 1 ,wherein engaging the tip of the airfoil within the tip-securing fixture comprises engaging each of a plurality of tabs extending from a radially outer edge of the tip of the airfoil within the tip-securing fixture; andwherein disengaging the tip of the airfoil from the tip-securing fixture comprises disengaging each of the plurality of tabs from the tip-securing fixture.3. The method of claim 2 ,wherein the plurality of tabs comprises a leading edge tab proximate a leading edge of the airfoil, a trailing edge tab proximate a trailing edge of the airfoil, and a center tab disposed between the leading edge tab and the trailing edge tab, the center tab having a bore extending radially inward from a radially outer side of the center tab;wherein the tip-securing fixture comprises a leading edge clamping assembly configured to be selectively engageable and disengageable from ...
