Machining accuracy of slow-feeding EDM wire-cut is one of major targets scaling processing properties.

慢走丝电火花线切割加工精度是衡量加工性能的重要指标之一。

Before EDM wire cutting die points of non_straight and non_arc lines, an arc for fitting the curve of the die point is necessary so as to calculate wire_cutting programming data.

电火花线切割非直线和非圆弧的模具刃口前，需先用圆弧拟合模具刃口曲线，以便计算线切割编程数据。

Then see all kinds of wire is damaged, because basically is the engine parts, metal material into the metal rod folksy is also very easy to produce edm.

其次看看各种线材有没有破损，因为发动机舱里基本上都是金属材质的部件，线材的破损处碰到金属也很容易产生电火花。
