| 摘 要： | 在分析NURBS曲线现有插补算法的基础上,着重研究了三次NURBS曲线实时插补技术。针对部分算法的不完整或效率低,提出了一种简单快捷的插补算法。采用NURBS曲线的矩阵表达式,将整个插补过程分解为插补预处理和实时插补。在插补预处理中完成了大量的计算,预处理的计算结果直接应用于实时插补,使插补算法满足了NURBS曲线插补的实时性要求,再辅以必要的轮廓误差控制,实现了加工速度自适应于加工路径的NURBS曲线直接插补。

| Abstract: | Based on analyzing the NURBS curve interpolation algorithm,the three NURBS curve real-time interpolation technology is researched emphatieally.In view of the partial algorithms which is incomplete and the low efficiency,a simple and quick interpolation algorithm is proposed.Using the matrix representation of NURBS curve,the whole interpolation process is divided into appropriate pretreatment and real-time interpolation.In the appropriate pretreatment,the system will achieve a large amount of calculation,and... |
