对自由曲面ＮＣ加工中刀具轨迹生成技术和干涉处理方法进行了分析，以曲面模型→刀具接触点数据→无干涉刀位数据为基本求解策略，研究开发出适用于带倒角平底刀无干涉刀具轨迹生成的新算法。该算法具有干涉检测彻底、处理效率高、稳定性好等优点。
The tool path generation technology and the interference processing method in NC machining of freeform surface are analyzed. Taking the surface model → tool contact point data → no interference position data as the basic solution strategy, the research and development of a tool suitable for the non-interference tool A new algorithm of trajectory generation. The algorithm has the advantages of complete interference detection, high processing efficiency and good stability.
