This interpolation module uses the popular and advanced nurbs interpolation technology . the procedures of math processing for nurbs , preprocessing for interpolation and real - time interpolating running on dsp are presented in this article . the interpolating procedure uses an advanced self - adjusting interpolation method , which can automatically adjust the length of interpolation according to machining speed , acceleration and the tolerance of bow height 插補模塊則采用了當今最流行最先進的nurbs插補技術,設計了nurbs數(shù)學處理程序,插補預處理程序,運行于dsp的實時插補程序,該插補軟件采用了先進的自適應插補方法,可以根據(jù)加工的速度,加速度,弓高誤差的要求自適應調整插補步長,同時采用了對插補點的預估算法,免去以往加工方法中求導的運算,大大降低了運算量,提高了加工速度。
