摘　　要：指出了硬质合金钻头刃口钝圆对切削加工的影响,说明了硬质合金钻头刃口钝圆的重要性,简要介绍了刃口钝圆的方法及常规的测量方法,提出了在Matlab中用最小二乘法拟合的数据处理方法来获得刃口钝圆半径值。与传统测量方法相比,此方法避免了常规测量方法所产生的人为的不确定因素,减少了由于测量系统的精确度引起的误差,可以准确地判断是否达到钝化参数的要求,对优化刀具结构设计、提高切削性能、增加刀具使用寿命有重要的作用和实际意义。The influence of hone edge radius of carbide drill bit during cutting was pointed out here,and the importance of hone edge was illustrated.And then,the measurement of hone edge and the way to measure were introduced briefly.The hone edge radius were acquired by a new data processing method of the least squares fitting,which can avoid the artificial uncertainties,reduce the errors caused by the accuracy of the measurement system in the conventional measurement methods,and it has an important significance for optimizing cutting tool structure design,improving cutting performance,and increasing tool life.
