ABSTRACT:
An adaptive control system for a machine tool or the like includes two pairs of thrust sensors for measuring radial and axial spindle deflection and a temperature sensor for measuring spindle bearing temperature. Data processing apparatus, typically comprised of a microcomputer, is coupled to the thrust and temperature sensors and regulates the spindle bearing preload and spindle axis feed rate in accordance with the radial and axial spindle thrust. The microcomputer simultaneously regulates the percentage of oil in the oil/air mixture lubrication mist sprayed on bearing contact surfaces in accordance with bearing temperature, thereby assuring optimum machine tool performance.
