<p>The method involves forming an auxiliary clamping structure for clamping of workpiece e.g. blade sleeves, at a workpiece holder (15) by a rotor section (6) and a feeder (3), which stay at a platform of a turbine blade (4). The blade is positioned at reference points and fixed at longitudinal sides of the platform. The workpiece is deformed and centrically positioned at the holder and is machined at a blade base structure. The clamping structure, feeder, rotor section, rotor clamping surface (12), a tapered recess (13), and a borehole (14) are separated from the machined blade. An independent claim is also included for an arrangement for implementing a method of finish-machining of base structure of a blade for an engine of a gas turbine.</p> |
