摘　　要：以砂轮磨削加工刀具的啮合运动为基础结合二值图像的处理方法,探索了一种方便快捷且准确求取整体铣刀容屑槽端截形的方法。该方法可以避开解析法求解非线性方程获取接触线的过程,直接通过啮合运动轨迹生成砂轮磨削刀具的空间包络,然后截取包络在刀具端截形上包络的曲线簇图像,转换成二值图像后,扫描图像的像素点提取整体铣刀容屑槽端截形,是理论上快速获取刀具容屑槽端截形,观察槽形轮廓和分析其相关参数的新方法,尤其适用于分析成型砂轮形成的立铣刀容屑槽。Based on the meshing motion of the wheel grinding tool and the processing method of binary image,this paper explores a convenient,fast and accurate method for obtaining the section of the end mill’s groove. This method avoids the process of obtaining contact line by solving the non-linear equation by analytic method,and generates the spatial envelope of grinding tool directly through meshing locus,then intercepts the image of curve cluster enveloped on the mill end section,converts it into binary image,and extracts the cutter end section of the overall milling cutter through the pixels of the scanning image. It is theoretically fast to obtain the end mill’s groove. A new method of sectioning,observing groove profile and analyzing its related parameters is especially suitable for analyzing the milling groove formed by forming grinding wheel.
