Beschreibung
Zusammenfassung:The invention relates to a blank casting for producing a turbine engine rotor blade, with a vane connected by a platform (4′) to a root (2′), said root having an axial machining allowance intended to be removed by machining from each of its axial extremities, characterised in that at least one of the axial extremities of the root (2′) comprises at least one transverse channel (14′) that extends over the entire transverse width of the root and whose depth is greater than said machining allowance. The invention also relates to the process for obtaining the blade by machining this blank casting.
