Abstract:
Process for determining the alignment of a body mounted to rotate around a lengthwise axis of the body with respect to a reference direction and including a position measurement probe, comprising the steps of calibrating the position measurement probe relative to the reference direction using a coordinate system that is external to the mounted body to be aligned and fixed relative to the location of said body, attaching the measurement probe on the end face of the body or at a longitudinal axis of the body on a surface essentially parallel to the end face of the body, performing position measurements in at least three measurement positions, each of which differs from the others by an angle of rotation of the body around the lengthwise axis of the body, with one position measurement at a time being taken, and using an evaluation means to compute the alignment of the body with respect to the reference direction from the measurement data gathered from the at least three measurement positions relative to said coordinate system.
