| 摘要: |
| 本文把微分几何中曲线与曲面之间的“切触”概念应用于复杂曲面的数控加工, 提出用圆柱铣刀或圆锥盘铣刀的外圆在五坐标联动中加工三维自由曲面的最佳切触条件。 |
| 关键词: 三维自由曲面, 三阶切触, 坐标联动 |

| Abstract: |
| This paper introduces a new theory that the concept in differential geometry of “contact”between curve and camber is applied to numbercally controlled machining sculpture surface. It puts forward the optimum contact condition for machining sculpture surface using cylindrical tool or bevel cutter with five coordinates co-operating. |
| Keywords: sculpture surface, third-order contact, coordinates co-operating |
