摘要: In this paper, an adaptive parametric curve interpolator with a real-time look-ahead function is developed for non-uniform rational B-spline curves (NURBS) interpolation, which considers the maximum acceleration/deceleration of machine tool. proposed interpolator, both constant feedrate and high accuracy are achieved while inconsistency reduced dramatically as well. order to deal around sensitive corners, introduced detect adjust adaptively. Two cases were respectively studied evaluate feasibility interpolator: one arc corner; other sharp corner.
