摘　　要：数字积分插补算法是在数字积分器的基础上建立起来的一种插补算法，易于实现多坐标联动，在数控系统中得到广泛应用。多数教材在讲述该算法时，在推导了用累加和表示积分值的过程后，没有进一步解释算法中各参数的物理含义，学生理解起来有困难．本文基于数字积分法的原理，详细阐述了算法中各参数的物理含义，并以数字积分直线插补算法为例做了进一步分析，便于学生掌握该算法的本质。The digital integrator interpolation algorithm is established on the basis of the digital integrator interpolation algorithm widely used, easy to implement multi-axis CNC system. Most textbooks in about the algorithm, derived with the accumulation and further explain the algorithm of the integral value of the process, there is no physical meaning of the parame-ers, the students understand difficult. Based on the principle of digital integration method, elaborated the physical meaning of the parameters in the algorithm, for example to do further analysis and linear interpolation algorithm of digital integration, to facilitate the students to grasp the essence of the algorithm.

关 键 词：数字积分插补算法 数控系统 物理含义
