摘　　要：本文基于刀刃曲线方程，推导了球头等法前角前刀面的几何模型及其数控磨削模型。该模型保证球头前刀面法前角相等，并可实现螺旋形前刀面与球头前刀面一次走刀加工。最后，通过计算实例及加工过程仿真验证了上述模型的可靠性。Based on equation of cutting edges, new geometric model and NC grinding model of rake face of ball end mill with constant normal rake angle are modeled. The normal rake angle can be constantly grinded and finished in one turn. At last, the validity of the models given in this paper is identified by example of grinding and computer simulation.
