摘要
在分析三次非均匀有理B样条(NURBS)曲线原理的基础上,提出了NURBS曲线的实时插补算法。该算法通过插补预处理以及合理的近似计算,大大减小了插补计算的时间;并且列出了插补误差和进给步长自适应控制,从而实现高速高精度插补加工。
A real time NURBS curve interpolation algorithm of Expander Tool is proposed on the basis of analyz three-times NURBS principle.This algorithms greatly reduced the the interpolated computer time by interpolated pretreatment and reasonable approximate computation; at the same time, it introduce interpolation error and step-length adaptive control,all of which makes the high-speed and high-precision interpolation processing of expander tool become true.
