本文详细地介绍了如何利用直线与圆的方程来计算转接小圆弧的中心尺寸,如何计算各段圆弧所对的圆心角;如何精确地计算二直线段的长度;并详细叙述了在普通铣床上用立铣刀加工曲线槽的工艺过程及操作方法。 经实践证明,计算方法正确无误,工艺过程合理,操作简便,取得了良好的效果。 This paper introduces in detail how to use the equations of line and circle to calculate the center size of small arcs and how to calculate the central angle of each arc. How to calculate the length of two straight lines precisely, Ordinary milling machine with an end mill curved groove process and operation method. The practice proved that the calculation method is correct, the process is reasonable, easy to operate, and achieved good results.
