ABSTRACT:
An apparatus for compensating for thermal expansion and contraction causing structural part size variations of machine components. The apparatus senses the displacement and temperature of various components of a machine 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 is responsive to the sensed temperature and converts various sensor outputs to the necessary correction signals for application to the motor causing the relative motion.
