Rotary table is widely used with multi-axis machine tools as a means for providing rotational motions for the cutting tools of the three-axis machine tools to be used for five-axis machining operations. In this paper, we present a comprehensive procedure for the calibration of the rotary table including: a) geometric error model, b) error compensation method for the CNC controller, c) error measurement method, and d) verification of the error model and compensation algorithm with experimental apparatus. The developed methods were verified through various experiments, showing the validity and effectiveness of the presented methods, indicating they can be used for the multi-axis machine tools as a means for calibration and precision enhancement of the rotary table.
