高速切削加工技术是一种先进的制造技术，具有强大的生命力和广阔的应 用前景，已成为切削加工的主流。数控插补技术是数控系统实现轨迹运动控制 的基础，插补运算是CNC系统软件实现运动控制的核心模块，插补算法的优劣 将直接影响到CNC系统的性能。因此，实现一种高精度和高速度的插补方法是 插补的关键所在。 本文在分析传统基准脉冲插补、数据采样插补的算法的基础上，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。 本文讨论的插补算法采用C++语言实现，并在VC++6.0的编程环境中实现 了插补算法的计算机仿真，验证了算法的正确性和可行性。(The high speed cutting is one of advanced manufacture technique,which has the powerful vitality and the broad application,and already became the mainstream of machining.The interpolation technology of NC is the foundation of path s control in the CNC system,and the interpolation operation is the core module of CNC system software,which comes the motion control true.The interpolation algorithm,whose function is good or bad,directly influences the performance of CNC system.So,a kind of interpolation method with the high accuracy and high speed is the key of interpolation. Based on analyzing the traditional pulse interpolation and data sampling interpolation,this paper emphasizes on the NURBS curve real-time interpolation technology.In view of the partial algorithms which is incomplete and the low efficiency,this paper propose a simple and quick interpolation algorithm.Using the matrix representation of NURBS curve,the whole interpolation process is divided into appropriate pretreat)
