| description | The invention relates to a device for the electrical discharge machining of at least one rectilinear cooling air passage (
6
) having a flared opening (
8
) in the wall of a hollow turbine vane (
2
). The inventive device comprises at least one forming electrode (
10
) attached to a first electrode holder and intended to produce the flared outlet opening. The forming electrode (
10
) comprises a first face(
28
a
) which is provided with a groove for guiding a rectilinear electrode (
7
) designed to drill the rectilinear part of the air passage (
6
), a median portion (
28
) with a constant section and a pointed end portion with a section that decreases between the median portion and the point of the forming electrode. |
