摘要
研究了一种自由曲面类零件数控加工中进给速度的优化方法。即依据曲面上一点的邻近结构对自由曲面进行简化,建立特定加工条件下简化的加工模型并进行加工实验,采集一定切削条件下简化模型的最佳进给速度,通过此匹配优化算法,对被加工的自由曲面与已建立的模型进行匹配和基于模型匹配的进给速度的优化,实现自由曲面加工中进给速度随加工条件的变化进行动态优化的目的。
The optimizing method of feed - rate for free - form surface parts in NC machining is studied. Free - form surface is simplified according to the. neighborhood form of one point on surface. Machining model of simplified is established and tested under special cutting conditions. The optimum feed - rate of simplified model is gathered. The free- form surface is matched to the model of established by using the matching optimizing algorithm. The feed - rate is optimized based on the matching of model. The purpose of dynamic optimizing for feed - rate following the varying of cutting conditions in free - form surface machining is realized.
