摘　　要：逐点比较法直线插补方法在开环数控系统中被广泛采用,但其存在插补误差大、直线光滑性差等缺点.针对以上问题,提出了改进的逐点比较法直线插补算法,避免了无穷大导数计算、多分支判断编程复杂等缺陷,提高了逐点比较法的直线插补精度.Point-to-point comparison method of straight lines is widely used in open loop control system,but it exists some weaknesses such as high interpolation error and poor smoothness of straight line.For above problems,an improved point-to-point comparison method of straight lines is given which can avoid shortages of counting the infinity of derivative and complex programming of many branches,and also improve the interpolation precision of point-to-point comparison method of straight lines.

关 键 词：逐点比较法 直线插补 插补误差
