摘要为提高2.5轴零件数控加工过程中的加工效率和加工精度，合理选择刀具直径组合是非常必要的。然而，目前刀具的选择主要依靠工艺人员的实际生产经验或结合大量的试验确定，代价昂贵。为解决上述问题，文章提出一种基于2.5轴零件数控加工刀具直径优选方法。首先分析了2.5轴零件的结构特点，将图形区域按照加工精度要求转换为二值图像，并利用相关方法获取图像骨架；然后采用拓扑细化法获取图像的初始骨架，并结合动态骨架法进行初始骨架的修正，获得图像的准确骨架，继而得到沿骨架加工时刀具的直径分布。针对型腔类零件数控加工的算例分析表明，采用本文方法能够快速获取给定刀具数量下的最优刀具组合和相应的加工轨迹，提高了加工效率。
