Abstract	A method for obtaining smooth, jerk bounded feedrate profile in high speed machining has been developed. This study proposes a NURBS interpolator based on adaptive feedrate control with a well developed lookahead algorithm. It is found that the values of the feedrate of the down stream sharp corner have profound effect on the feedrate of the upstream sharp corners causing a ripple effect (RE). By using a windowing scheme the feedrate profile obtained after lookahead is re-interpolated to obtain a continuous velocity and acceleration profiles which reduces the jerk related problems. This is compared with the adaptive NURBS interpolator to show the effectiveness of the proposed method. Simulation results indicate that the consideration of ripple effect is important in avoiding jerk and thereby increasing the machining accuracy.
