It is used on the control software of the nc carver instead of the pulse increment interpolation and realized by C-language.

在数控雕刻机控制软件中用直接函数计算法取代脉冲增量插补，能够满足高速高精度的要求，并用C语言编程实现。

And from the angel of output format of interpolation calculation, it can be divided into reference pulse interpolation (or pulse increment interpolation) and data sampling interpolation.

从输出的数值形式来分，有基准脉冲插补(又称脉冲增量插补)和数据采样插补。

Study the dot-comparison in pulse increment and develop the line and arc interpolation.

研究了逐点比较法，并编制了平面的直线插补和圆弧插补程序。
