一种复杂平面型腔加工区域自动识别的算法

A Self-discrimination Algorithm Used in the Complex Planar Milling Contour

根据平面型腔的造型数据 ,自动识别并提取出需要进行数控加工的区域 ,按照环与环的位置关系 ,采用两次判别的方法。第一次为粗判别 ,得到加工区域的初步信息 ;在此基础上进行精确判别 ,生成加工区域的树状数据结构 ,获得待加工区域。算法适用于多个不连通区域的识别 ,为一次生成多个不连通区域的加工刀具轨迹奠定了基础。

Based on the model data of the planar contour, the milling regions can be gotten. It introduces the distinguishing method, first deals with the milling regions, and then generates the data tree for these regions by the accurate treatment. This algorithm is suitable for multi-unconnected curves, and can be used in tool path generation.
