圆锥、圆柱正交相贯线最右点的准确求法

利用计算机辅助设计给出了一种新的圆锥、圆柱正变相贯线最右点的求解方法。原有的方法求解圆锥、圆柱正变相贡的最右点，常利用侧视图中圆柱的积聚性，过锥顶作积聚圆的切线，再求出该切点在V面的投影，但这一方法求出的并非准确的最右点。利用解析方法对新方法进行分析验证。

An Accurate Solution of the Furthest Right Point of the Pro-cut Line of Taper & Column

The article makes a correction to a prevalent fault in engineering drawing science at present. Where taper and column pro - cuts, it usually utilizes characteristic of gather in side elevation to seek the cut line in the furthest right point, passing the top of taper to make cut line of gather circularity, finding out the cutting point in shadow of V side, which was thought that the point should be the furthest right. However, it is not correct. The article gives an accurate solution of finding the cut line in the furthest right point, and makes an analysis by analytics.
