| Abstract: | Based on the concept of two-step recursive interpolation, a new algorithm for interpolating a 3-D elliptic arc has been developed. It is only necessary to perform the addition and shift operation and no multiplication or division is required. It is an extension of high speed interpolation for a spatial circular arc. The stability and errors of the algorithm are discussed. |

| Keywords: | : numerically controlled machine machining interpolation elliptic arc stability error |
