摘　　要：基于非共轴螺旋面钻尖的刃磨原理,建立了刃磨参数的数学模型。根据钻尖几何参数与刃磨参数之间的关系,分析了刃磨参数的功能、可控性和敏感性。结果表明:、β和S对几何参数最敏感,通过将和S设定为常数,可解决刃磨参数冗余问题,精确求出具有唯一性的刃磨参数值。Based on the grinding principle of non-coaxial helical micro-drill point, the mathematical model of grinding parameters is established. According to the relationship between the drill-point geometry and grinding parameters, the functions, controllability and sensitivity of grinding parameters are analyzed. Results show that the grinding parameter φ,β and S are most sensitive to the geometric parameters. By setting φ, and S as constants, the redundancy problem of grinding parameters is resolved, then the only grinding parameter values can be calculated exactly.
