本文结合实例分析对比了电极挤压机型咀曲线的几种设计方法－－圆弧法、样条插值法、二次曲线法和双曲线法，分析表明变换坐标的双曲线法优于其它方法。
By comparing and analyzing the designing methods of the curve for elec-trode extruder mould-mouth----arc method,spline interpolation method,conicmethod and hyperbola method,we concluded that the hyperbola method is better thanthe other methods.
