In this paper, unit moving trihedron is first constructed for a point on the surface of a revolution ellipsoid. 摘要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. 对回转车削三面体的过程进行了运动学分析,建立了刀尖相对于工件的运动方程,计算了用该方法加工三面体零件时的各个参数。
irregular angle, right and reverse side, trihedron etc. 多角形、正反面、三面等。
