摘要
在机械制图中,当轴线正交的两圆柱相贯时,常常采用“用圆弧代替相贯线的投影”的近似画法。本文对此法的作图误差进行分析,研究其误差分布规律,并推算出它的最佳适用范围。
This paper analyzes the constructional error in the approximate drawing adopted, i.e. substituting an arc for the projection of the intersecting line, when two cylinders whose axes are perpendicular to each other are intersecting, and investigates into the law of its errors, and determines optimum application range in mechanical drawings.
