摘要
Rotary tables are widely used with multi-axis machine tools as a means for providing rotational motions for the cutting tools on the three-axis machine tools used for five-axis machining operations. in this paper, we present a comprehensive procedure for the calibration of the rotary table including: geometric error model; error compensation method for the CNC controller; error measurement method; and verification of the error model and compensation algorithm with experimental apparatus. The methods der eloped were verified by various experiments, showing the validity and effectiveness of the presented methods, indicating they can be used for multiaxis machine tools as a means of calibration and precision enhancement of the rotary table.
