| 摘 要： | 刀具轨迹生成是自由曲面零件数控加工中重要的研究内容.本文分析了自由曲面数控加工中常用的刀具轨迹生成策略和方法,设计和实现了一种基于Z-map结构的自由曲面无干涉刀具轨迹生成算法.本算法采用进化算法进行刀具干涉检测,不仅解决了生成刀具轨迹时因走刀步长不合理而产生的过切问题,而且也确保了生成的刀具轨迹为无干涉刀具轨迹.

| Abstract: | Tool path generation is an important research content in NC machining of free-form surfaces. In this paper,according to analyzing tool path generation strategies and algorithms,a new tool path generation algorithm based on Z-map model is designed and implemented. Using evolutionary algorithm to detect tool interference not only avoid the over-cut problem resulting from unsuitable forward step during tool movement,but also ensure the generated tool path is interference-free tool path. |
