用于钻槽的砂轮轮廓通常采用间接法设计，根据所需的钻槽来确定砂轮轮廓。本文提出了一种自适应的、直观的钻槽直接建模方法。总结如下：假设具有解析定义轮廓的砂轮绕静止的钻头作螺旋运动；该沟槽是由砂轮轨迹与工件之间的重叠部分产生的。计算结果与生产样品的测量数据吻合良好，验证了其有效性。
A grinding wheel profile for drill fluting is usually designed by the indirect method, defining the wheel profile by the desired drill flute. This paper presents an adaptive and intuitive direct method for drill flute modelling. It is summarized as follows: the grinding wheel, with analytically defined profile, is assumed to be moving helically around the stationary drill; the flute is generated by the overlapping part between the wheel locus and the workpiece. Its validity is verified by good agreement between the results computed and the data measured on the samples manufactured.
