【摘要】 提出了一种使球头模具铣刀具有良好切削性能，可以大大改善球顶点及其附近处切削条件的刀刃构造形式和前刀面形状；根据包络原理详细分析和研究了成形这种球头铣刀刀刃及前刀面的磨削（或铣削）系统的合理运动方式，并导出了各运动间的函数关系；给出了一计算实例。更多还原

【Abstract】 The ball-end milling process is used widely in the machining of free-form surfaees in the aerospace and die / mold industries.Firstly,the type of cutting edges and rake faees of ball-end mills is presented with enough good cutting condition,Secondly,ways are studied to deteimine the motion function of grinding(or milling)system when the edges and rake faces of mills are foimed with a taper cup wheel.Lastly,an example showing a mills parameters and motion functions is given.更多还原
