椭圆(Ellipses)、双曲线(Hyperbolas)、抛物线(Parabolas)是三种未退化的圆锥曲线,其中椭圆和双曲线也被叫做共焦圆锥曲线,因为两者都有对称的中心点。

Then the line, the arc and the parabola are adopted to form a fitted curve. Finally, the curved face is aggregated by each curve.
对于二轴联动的数控加工中心,实现加工曲面的方式一般是采用球头铣刀,通过把曲面剖切成平行于某轴的平面曲线,再用直线、圆弧、抛物线去拟合该平面曲线,最终对每一条曲线加工集合成曲面。
