This report proposes the suppression method of the stick motion at quadrant changes by the real-time inverse transfer function method without identifying the parameters previously. The dynamic characteristics of 2-axis NC table are identified by real-time calculation as the second regression function with consideration of variables for parameters during motion. The real-time compensation is executed by the identified parameters that show the characteristic values at quadrant changes. The trajectory error by the proposed method has been suppressed 37.1% of that by the conventional feedback control during air cutting. As the result of applying to the circular interpolation machining, the contoured profile of the workpiece by our method shows the suppression of 43.6% of the stick motion.
