Research on creating interference-free contrail of EDM generating machining die cavity

针对电火花创成加工具有复杂自由曲面的模具型腔 ,提出利用简单圆柱形电极在五坐标联动电火花机床上加工自由曲面无干涉电极运动轨迹的生成算法 ,并对电火花加工过程中的电极损耗进行了补偿 。

In this paper, an algorithm of interference-free electrode motion contrail for 5-axis machining of freeform suffaces using simple column shape electrode is proposed toward EDM generating of die cavity with complex freeform sufaces. And the spoilage of electrode in the machining process is compensated in this algorithm. So the machining quality and precision is advanced greatly.
