Abstract:
    A method of inspecting the profile of the connection zone between the cylindrical portion and the taper of a turbomachine part, the surface profile of the part being geometrically defined by at least one first zone corresponding to the taper of the part, at least one second zone corresponding to the connection between the cylindrical portion and the taper of the part, and a third zone corresponding to the cylindrical portion of the part, the method consisting in measuring the surface profile of the part; from the measured surface profile, modeling the contact pressures that apply to the surface of the part for each of its zones; and comparing the contact pressures modeled for the second zone of the surface profile of the part with predefined threshold values.
