摘要:

根据路径的拓扑结构和参数,从算法简单程度、计算量、效率及加工精度等方面,分析了国内外现有的数控加工刀具路径规划的方法及优缺点,结合环形刀及被加工曲面的局部几何特征,提出了一种新的刀具路径规划方法。并通过仿真实验证明,此方法在加工复杂曲面时,能够充分发挥五轴数控加工的优势,大大减小相邻路径间的依赖性,有效地避免误差叠加和放大的缺点。

Based on the topology and parameters of tool path planning, this paper presents a new method to plan tool path in high-speed machining. It considers both the conditions of maximum cutting efficiency and average machine width. So, the dependence between two adjacent tool paths is greatly reduced. And the magnified errors can be avoided effectively, which play more advantages in five-axis CNC machining.
