Abstract:
A method for manipulating the position and size of a diameter of a heated, rotating object, the method comprising the steps of:providing an object having an axis;rotating the object about its axis through a series of angles;heating at least a portion of the object to a temperature sufficient to render the heated portion deformable by a force;providing an imaging device;imaging the heated portion of the object radially with the imaging device at a predetermined axial location within the heated portion to determine a length of the diameter of the object at the axial location and to determine a distance between the center of the diameter of the object at the axial location and the axis for each angle in the series;comparing the determined length of the diameter at the axial location with a desired diameter length to obtain a diameter length error for each angle in the series;comparing the determined distance between the center of the diameter and the axis to a desired diameter center distance to obtain a diameter center distance error for each angle in the series;applying a predetermined radial force to at least one distinct predetermined radial location on the object at the predetermined axial location to cause the object to conform to the desired diameter length and the desired diameter center distance based upon the determined diameter length errors and the determined diameter center distance errors.
