Differing from previous studies, the new method was derived from the idea of motion of moving trihedron along a predesigned path of contact on the predesigned (theoretical) tooth surface.───以往的齿面加工方法不同，在新的齿面展成方法中，齿面展成运动是在沿预定接触迹线的曲面活动标架下设计的。
In this paper, unit moving trihedron is first constructed for a point on the surface of a revolution ellipsoid.───以旋转椭球体面上某点为原点建立一个大地坐标单位活动坐标架。

Aimed at a kind of rotary cutting machine, the machining process of trihedron cutting is kinematically analyzed, and the moving locus equations of cutting edge are deduced.
