Geometrical relationship among the length of triangle sides is used to determine the Angle of rotation, the cone can be machined without using measuring instrument.
利用圆锥三角形边长的几何关系来确定转动角度，可以不用测量仪器加工出圆锥体。
In this manner, the shapes and sizes of the chips are determined at least in part by the modulation cycle, and particularly the length of time the cutting tool is engaged with the body being machined.
按照这种方式，碎片的形状和尺寸至少部分由调制循环确定，尤其是切削工具的时间长度与正被机械加工的物体衔接。
