摘　　要：基于球头刀刃与螺旋刃在交点处应满足一阶连续的条件,推导出球头平面刀刃曲线及可与螺旋前刀面光滑连接的球头平面型前刀面几何模型;进而建立了球头平面型前刀面的数控磨削模型。磨削过程的软件仿真验证了上述模型的正确性。为实现复杂刀具的CAD/AM提供了方法模型。Based on Restrain of Continuity of helical cut edges, new geometric models, along with NC grinding model, of planar cutting edge and planar rake face of ball end mill are modeled. The planar rake face can be smoothly connected with the helical rake face. At last, the validity of models given in this paper is verified by examples of grinding and software simulation. The research may also provide a general picture of CAD/CAM process of complex tools.
