摘要： The invention relates to a device for holding a turbomachine blade for the purposes of machining, comprising a holder (1) comprising at least one housing (5) in which at least one unit formed of two jaws (22, 23) having an opening into which to fit a blade aerofoil is removably mounted. The unit comprises six support points for the aerofoil. The device comprises a moving pressing finger (43), intended to press against a pressure-face or suction-face surface of the blade, which finger is moved by actuating means (12, 17) so that, when the blade is in the clamped position, the pressing finger (43) presses the aerofoil firmly against the support points of the unit, which is itself pressed firmly against the holder (1).

摘要： The present invention relates to a method for adjusting a predetermined contour of a turbine blade root (4) comprising a main salient edge defined by a determined interior angle. According to the invention, the following successive steps are performed: A/ the main edge of the contour is chamfered in order to obtain two auxiliary salient edges the associated interior angles of which are respectively greater than the interior angle of the main edge; and B/ the auxiliary edges obtained are blunted in order to fine-tune the contour of the blade root (4).
