| 摘 要： | 本文介绍了ＣＮＣ系统采用两次插补方式，使用的一种新的ＤＤＡ圆弧插补公式：双ＤＤＡ圆弧插补公式。对该公式的误差分布进行了详细的理论推导和证明，并得到了插补点坐标的一般表达式，而且结合两次插补原理，推导出了双ＤＤＡ圆弧插补公式的弦拟合误差的分布范围。

| Abstract: | This paper introduces a new DDA algorithm: twin DDA algorithm. The provement and derivation of this algorithm are described in details. The gerneral equation of interpolated point coordinates is derivated for fine error analysis and the distributed zone of chord error of twin interpolate method of this algorithm is also presented in this paper. |
