Claim:
1. A method of finishing aerodynamic surfaces of a component for a gas turbine engine to produce a finished component from a rough component, the method comprising: scanning aerodynamic surfaces of the rough component to obtain scanned electronic 3-D data representing the scanned surfaces of the rough component; identifying, using the scanned 3-D data, specific features to be removed from the rough component; generating a bespoke tooling path to remove the features identified for removal; and machining the rough component according to the generated bespoke tooling path so as to thereby produce a finished component, wherein the step of identifying the features to be removed consists of comparing the scanned 3-D data at a given position on the scanned surface to the scanned 3-D data at neighbouring positions on the scanned surface so as to determine the local shape of the scanned surfaces.
