  • Method for controlling perpendicularity of a cylindrical part, such as a nuclear fuel pellet
    Patent number: 6449034
    Abstract: In order to control the perpendicularity of a component (10) such as a nuclear fuel pellet, this component is placed upon a support plane and measurements are taken, by means of two pairs of laser micrometers (A1, A2; B1, B2), of the distances separating diametrically opposed generators of the component from a rod of reference (T, T′), at two different levels and in two measuring planes (P, P′) perpendicular to each other. From this is derived a maximum out-of-true perpendicularity of the component being controlled.
