This CNC system employs differenceinterpolation method for interpolation calculation, which can directly interpolate all of conic.
插补计算采用了差分插补法，能对所有的二次曲线进行直接插补。

In this paper, for example by the straight line, circle and parabolic, introducing the conversion process from ISO code to differenceinterpolation code.
本文还以直线、圆和抛物线为例，阐述了ISO代码到差分插补代码的转换过程。

The quadratic monotone interpolation characteristic difference method is proposed to overcome these defects.
