GROSS FOUNDRY FOR THE PRODUCTION OF A TURBOMACHINE ROTOR BLADE AND ROTOR BLADE MADE FROM THIS BRUT

摘要

The invention relates to a caster for the production of a turbomachine rotor blade, comprising a blade connected by a platform (4 ') to a foot (2'), said foot having an axial excess thickness intended to be removed by machining at each of its axial ends, characterized in that at least one of the axial ends of the foot (2 ') comprises at least one transverse groove (14') which extends over the entire transverse width of the foot and whose depth is greater than said overthickness. It also relates to the blade obtained by machining of this casting and the corresponding manufacturing process.
