Abstract

A method of machining a blade in a three-dimensional machining center, the blade including an airfoil, a platform including upstream and downstream supports formed respectively under the upstream and downstream portions thereof for supporting a sealing liner, a blade root, and a stilt interposed between the platform and the blade root, the method including the upstream and downstream supports constituting two bearing points for a six-point positioning system for positioning the blade in the three-dimensional machining center.

Claims (6)

1 - 4 . (canceled)

5 . A method of machining a blade in a three-dimensional machining center, the blade comprising an airfoil, a platform including upstream and downstream supports formed respectively under the upstream and downstream portions thereof for supporting a sealing liner, a blade root, and a stilt interposed between the platform and the blade root, the method comprising:

the upstream and downstream supports constituting two bearing points for a six-point positioning system for positioning the blade in the three-dimensional machining center.

6 . A machining method according to claim 5 , wherein the bearing points are formed on a suction side of the stilt.

7 . A turbine engine including a plurality of blades obtained by the machining method of claim 5 .

8 . A turbine engine including a plurality of blades obtained by the machining method of claim 6 .
