Abstract

The article briefly deals with a algorithm of adaptive interpolation for NURBS curve which NURBS curve reache any point, while, the feed rate can keep costant as during the whole interpolation process. The interpolation of NURBS curve should be finished. The simulation results show that the algorithm is correct; it is consistent with a NURBS curve interpolation requirements.
