  • Patent number: 9027245
    Abstract: A method for producing a solid component which in succession includes deforming a metal bar by forging using two dies in order to obtain an intermediate component including two fins one on each side of a solid part capable of forming the base of the metal reinforcement, the two fins being at a divergent angle ?; deforming the two fins of the intermediate component, altering the divergent angle ?, so as to obtain the final shape of the turbomachine blade leading edge or trailing edge metal reinforcement.
    Type: Grant

  • Publication number: 20120124834
    Abstract: A method for manufacturing a part by forging, including producing a semifinished part by precision forging and polishing the part by an abrasive strip, compliant geometric characteristics of the part to be obtained being predetermined in a theoretical model. The method includes: measuring the geometrical characteristics of the semifinished part after the forging operations and comparing the characteristics with the theoretical model; determining noncompliant areas on the surface of the part; determining the amount of material to be removed from each noncompliant area to make the area compliant; and polishing the part using the abrasive strip, controlling the strip so as to remove the amount of material from each noncompliant area. The method can be used for example for polishing turbine engine fan blades.
