Abstract (en)
[origin: EP1840230A2] The method involves arranging a cylindrical part (1) of an aeronautic turbomachine case e.g. compressor casing, in a pot heater (5), and heating the cylindrical part to a hot thermal processing temperature. An inner sizing die (8) is installed inside the cylindrical part during its maximum structural recess, where the sizing die has a diameter higher than a diameter of the cylindrical part. The cylindrical part is cooled to a temperature lower than an ambient temperature of a maximum structural recess. The inner sizing die is extracted. An independent claim is also included for a cylindrical part sizing device comprising a model.
