摘　　要：三棱轴、孔一般较多的用于机械的传动部分,用于运动和力的转化,而三棱形内外圆磨削数学模型的建立是开发三棱磨床的基础。由于三棱形轮廓为非标准圆,这就导致实际磨削点不在砂轮圆心和工件几何中心的连线上,为了知道工件转动的角度和砂轮的实际运动之间的关系,建立了三棱形内外圆磨削数学模型,生成了理论运动轨迹。The three prism shafts and holes are most used in mechanical driving part generally,used for motion and force transformation.The internal and external milling mathematical model of three prism is the basic of the three prism grinding machine＇s developing.Because the counter of the three prism is a Nonstandard circle ,this lead to the practical grinding point is not on the line lock of grinding wheel＇s circle center and workpiece＇s geometric center.For knowning the relation between workpiece＇s rotational angle and grinding wheel＇s actual moving,we build the internal and external milling mathematical model of three prism and produce the theoretic＇s moving track.
