本文提出了细分曲面数控刀具路径生成的方法和算法。我们选择Loop曲面作为细分曲面。根据细分曲面的LoD （Level of Detail）特性，给出了包含粗切和精切的路径规划。我们生成一个覆盖极限表面的粗网格来实现粗切。对于精切，我们使用球头铣刀和偏移刀具接触数据来生成刀具位置数据。在这两个步骤中，我们使用了Z-map模型，并提出了一种碰撞检测/校正方法来实现这两个步骤的无干扰。我们实现了我们的方法并给出了加工结果。这两种刀具轨迹都是快速自动计算的。
In this paper we propose methodologies and algorithms of NC cutter path generation for subdivision surfaces. We select Loop surface as the subdivision surfaces. A path plan including rough cut and finish-cut is developed based on the LoD (Level of Detail) property of subdivision surface. We generate a coarse mesh that covers the limit surface to implement the rough cut. For finish-cut we use ball-end mills and offset cutter contact data to generate cutter location data. In these two steps we use a Z-map model and a collision detection/correction method is presented for the interference-free of these two steps. We implement our methods and present machining results. All of these two kinds of cutter paths are computed rapidly and automatically.
