摘　　要：以普通麻花钻前、后刀面的数学模型为基础,建立了普通麻花钻后刀面锥面刃磨时各几何要素的平面像图;应用平面表像法,推导了钻头结构参数与刃磨参数之间的关系;为了由给定的结构参数计算刃磨参数,将求解关于刃磨参数的超越方程组问题,转化为计算结构参数误差平方和的最小值的优化问题,并用Matlab提供的优化函数进行计算.实体造型证明该方法计算结果是正确的.Based on the mathematical models of the flute surface and the flank of standard twist drills, the relevant planes and edges of the drill during conical point grinding are mapped on a projection plane. With this planar displaying method, the relations between the drill＇s structural and point grinding parameters are deduced. To calculate the point grinding parameters from the given structural ones, solving coupled equations with point grinding parameters is transformed to solving the minimum of the sum of the squares of structural parameter deviations. The calculation is conducted with Matlab and verified by model simulation.
