An Improved Adaptive Interpolation Scheme for NURBS Curve

Abstract:

This paper proposes an improved adaptive NURBS curve interpolation scheme, which keeps a constant feedrate most of the time and adaptively changes feedrate with consideration of machine dynamics. It reserves the advantages of adaptive planning, which has a shorter machining time and a better machining performance, and removes abrupt feedrate changes at the beginning and end of sensitive corner. Furthermore, this method reuses the previous interpolation values during look-ahead planning rather than discard them.
