相贯线在数控加工中的解析求法

The Solution of the Intersection Line in NC Machining

相贯线是画法几何中的重要内容,在画法几何中我们一般用作图法来求,本文利用数学中的解析法求得平面与立体及立体与立体之间相贯线的函数表达式,以便于利用在数控机床的机件加工中.

The intersecting line is an important element in descriptive geometry,in which we usually use drawing method to find the solution.The author uses the analytical method in mathematics to find the function expression of the intersecting lines between plan and geometries,and the lines between geometries,which could be applied in NC machining.
