Abstract: A thermal displacement comensating apparatus capable of compensating for the thermal displacement of the main spindle of a machine tool is disclosed. A feed back scale and a measuring head are provided in order to detect the actual position of the front end portion of the spindle head. Furthermore, a distance sensor is provided for detecting the thermal extention of the main spindle with respect to the spindle head. The output signal from the distance sensor is used for modifying the present position detected by the measuring head or modifying a commanded target position. With this arrangement, a tool attached to the front end portion of the main spindle is moved to the commanded position regardless of the thermal displacement of the spindle head and the main spindle. Another type of compensation apparatus is also disclosed, wherein the measuring head is mounted on a mounting rod, and the mounting rod is automatically moved so as to maintain the distance between the measuring head and the front end surface of the main spindle at a constant distance. With this arrangement, actual position of the front end surface of the main spindle can directly be detected regardless of the thermal displacement of the spindle head and the main spindle.

Abstract: A computer based system supporting plant operators in carrying out nearly routine predetermined procedures, monitors plant instrumentation parameters and processes the gathered information to detect satisfaction of initial conditions to the state change. Once the state change is started, the system then compares the sequence of observed changes in the plant with a preprogrammed sequence and alerts the operators to any undesirable deviations from the preplanned sequence by providing appropriate attention grabbing displays on a system monitor. The system also continuously monitors constrain­ing conditions and alerts the operator when the system moves toward an undesired state.
