摘　　要：设计直纹面组合刀头,对盘形齿轮铣刀后刀面的数控磨削加工进行仿真。首先根据后刀面设计的理论公式,提出参数化设计方法,给出了在不同前后角参数下后刀面磨削点坐标计算公式及UV网坐标。分析、计算出磨削过程中对应的旋转轴数据,并推导出砂轮半径补偿计算公式。然后,用曲率方法分析磨削时的局部干涉现象,推导出避免局部干涉的砂轮半径可选择范围。最后基于VC、OpenGL平台给出了后刀面网格图和砂轮中心加工运动轨迹图。A dado head with ruled surface is designed,and simulation of NC（numerical control） grinding of the flank of a disk milling cutter is presented.First,with the theoretical formula of the flank,the calculation formula of point grinding and UV mesh are given with parametric design method.Data of the rotation axis in grinding process are analysed and figured out,and the formula of radius compensation of a wheel is deduced.Then the local interference is analysed with curvature based method,and the range of radius of grinding wheel check with noninterference grinding is derived.Finally,in VC and OpenGL,the drawings of flank mesh and the machining path of the center of the grinding wheel is given.
