Abstract

Time grating is a novel displacement sensor which employs time to measure space. A new predictive method for predicting the dynamic angular displacement of CNC rotary table is presented with time series. In addition, feedback interface for rotary transformer is designed to update data speed for time grating in the measurement process. Experiment results prove that forecast error for acceleration range from -0.00026″/ms² to 0.00028″/ms², and forecast angular displacement error is within ±2″.
