Notes:
Time grating displacement sensor is briefly introduced for measuring space with time.The measured values of time grating will not update during the measuring period. To use the sensoras position feedback component for CNC rotary table positioning servo control, this paper firstlyintroduces prediction conception to measurement field, and predictive measurement method isfirstly proposed. Predicted values are derived form past measured values and the prediction error iscorrected in real time using the new measured values. The positioning accuracy of the CNC rotarytable is improved greatly. Experiment results conform the validity of the proposed method
