| 摘 要： | 在CNC加工中,直线段和圆弧是加工路径的重要组成部分.而圆弧样条的段数和曲线的保形性,是比较重要而且富有实际意义的.提出了一种改进的G1圆弧样条保形插值算法,该算法在型值点列满足较弱的条件下,具有圆弧段数较少,并且保形的特点.

| Abstract: | In CNC machinery, NC tool paths are always made of circular and straight-line segments. The segment number of ares, and the shape-preserving property are usually important and practical. An improved G^1 shape pre serving arc interpolation algorithm under a weak condition is introduced, which can keep the shape of original data well and the segment number of circular arcs is less than that of data points. |

| Keywords: | arc splines interpolation shape-preserving |
