SUMMARY
As one of the international industrial standards of CAD system, NURBS curves play an increasing role in the application fields of computer-aided geometric design (CAGD) with the wide application of this geometric model. To improve machining accuracy and efficiency, Yeh and Hsu adaptively adjust the feedrate considering the constrained chord error, which improves the contour accuracy of parametric curve interpolation. Jia et_al proposed a NURBS interpolator under kinetic characteristics and contour error constraints, in which the feedrate remained constant in most areas and only changed smoothly in areas with large curvature, but the . . .
