本文讨论了圆锥曲面中在工程中应用得最广泛的旋转锥面。并采用平行移轴与转轴的方法,建立了旋转锥面曲线族解析表达式,描述了该曲线族随截平面与X轴夹角α变化的规律,从而精确的确定了该曲线族的轨迹。
This article discusses the most widely used conical surfaces in engineering. By using the method of parallel shift axis and rotation axis, the analytic expression of rotating cone curve family is established. The rule that the angle family changes with the angle α between the cutting plane and the X axis is described. The locus of this curve family is precisely determined.
