<p>An apparatus for compensating for thermal expansion and contraction causing structural part size variations of machine components (10). The apparatus senses the displacement and temperature of various components (P, 14) of a machine (10) which are designed to move relative to each other along one axis and adjusts this motion in predetermined manner depending upon the sensed displacement and temperature. A programmed control system (58) is responsive to the sensed temperature and converts various sensor outputs (50, 52, 54) to the necessary correction signals for application to the motor causing the relative motion.</p> |
