Abstract
A process for geometrical construction of a flash land is provided for a flash land that is to be provided in a die for forging of a turbomachine vane, in accordance with determined parameters, where the vane includes a blade. The process includes choosing at least three reference planes corresponding to a root, middle and tip of the blade. At least three reference sections of the blade in reference planes corresponding to the root, middle and tip of the blade are chosen in the reference planes. A length of the flash land and a shrinkage distance for the three reference sections are determined in the reference planes. Intermediate sections of the flash land and the corresponding flash gutter of the flash land from the reference sections are constructed by interpolation in the predetermined planes.
