| 摘 要： | CAD/CAM系统中复杂曲面数控加工刀轨的计算能力在工业中有极其重要的作用。介绍一种复杂曲面五坐标加工轨迹生成及干涉处理算法，即把曲面用小三角片离散逼近，并用连通图建立所有三角片之间的拓扑关系，在此基础上生成刀轨，并进行干涉检查及刀位修正。

| Abstract: | NC machining path of sculptured surfaces in CAD/CAM systems plays a key role in manufacture. This paper describes a new algorithm for 5 axis machining of sculptured surfaces and the algorithm for gouge free. The approach includes (1) the tessellation of the parametric surfaces into triangles, (2) building topological relation between triangles, (3) 5 axis tool path generations and (4) interference detection and tool position correction. |

| Keywords: | NC machining sculptured surface 5 axis machining gouge avoidance |
