Apply fuzzy interpolation method to calibrate parallel machine tools

A fuzzy interpolation method is proposed to simplify the calibration process for parallel machine tools. Either inverse or forward kinematic models need to be used in the traditional calibration methods to perform the identification and compensation of the pose errors for parallel machine tools. Instead of using a model, the proposed method presents a modeless technique combined with the fuzzy interpolation method to obtain the same or higher calibration accuracy when a small workspace is adopted.
