摘　　要：插补算法是数控技术的核心。文中研究了插补算法中三种典型的基于直线逼近的曲线插补算法,通过其在MATLAB上进行分析,得出等直线逼近的插补算法和等步长逼近插补算在误差上优于等误差逼近插补算法,等误差逼近插补算法在走刀次数优于等直线逼近的插补算法和等步长逼近插补算,同时它们在算法在运算上也比较简单,更加具有普遍意义。Interpolation algorithm is the core of numerical control technology. Matlab is used to study the interpolation algorithm of three typical curve interpolation algorithm based on linear approximation. It is concluded that linear approximation interpolation algorithm and step approximation interpolation calculation on error are superior to the error approximation interpolation algorithm, the feeding times of error approximation interpolation algorithm are superior to the linear approximation interpolation algorithm and step length approximation interpolation calculation. These algorithms are also simple and universal in operation.
