摘要
提出并实现了在CNC系统中完成曲面交线加工刀具轨迹直接插补的构想,可极大提高CNC系统的几何轨迹控制能力和使用性能.给出了一个适用于球头刀加工的插补算法及其.加工误差估计,证明了算法的稳定性.理论分析和实践表明,该算法精度高、计算量小且稳定.
The new idea that completing the tool-path interpolation for sculptured surfaces intersection machining in CNC system is presented and realized in this paper. The geometric path control ability and performance of this CNC system is greatly enhanced. An interpolation algorithm suitable for ball-end cutter and its machining error estimation as well as its stability analysis are given. Theoretical analysis and practice demonstrate that the algorithm possesses high accuracy and small and stable caculating amount.
