摘要
机械制图中,相贯线的求解是一个重点。一般作相贯线主要采用表面取点法和辅助平面法。理论 上相贯线是由无数个点组成,但作图时只作几个相贯点,然后由点连成线,因此作出的相贯线不准确。本文以两 相交圆柱为例,探讨用数学方程式精确求解相贯线。
It is an emphasis that the solution of two intersected objects' intersectant line in mechanical drawing. The way to find the solution of intersectant line is to gain the dot of object's face or use the auxiliary plane. The intersectant line is made up of a lot of dots. When one draws the intersectant line, he only draws a few dots and the intersectant line made up of the few dots. So the intersectant line is not precise. The paper, taking two intersected cylinders as example, inquires into the solution of precise crossed line with mathmatics equation.
