基于接触区域自适应调整的圆弧头立铣刀后刀面磨削轨迹精确计算方法OA北大核心CSTPCD

In order to ensure the machining accuracy of circular-arc end mill flanks,a grinding trajectory accurate calculation method for circular-arc end mill flanks was proposed based on contact area adaptive adjustment.Firstly,the mathematical model of the flank was constructed through struc-tural feature decomposition of the circular-arc end mill.Then,by calculating the grinding contact area between the grinding wheel and the flank,the grinding wheel posture was adaptively corrected to a-void grinding interference,which realized the accuracy and consistency of flank geometric parameter control and ensured the smooth connection of the curved surfaces.Finally,based on the implement of VC++platform algorithm module,the effectiveness of the proposed algorithm was verified by machi-ning simulation and grinding experiments.
