Abstract By combining graphic method with computing method, CAD method for design of profile of formed grinding wheel was presented based on mesh principle and the idea of reverse engineering. By making a series of cross-section perpendicular to the axial line of the formed grinding wheel, contact points between the grinding wheel and the helical flute of the milling cutter were obtained. After connecting those points, the contact line was gained and then after rotating this line by 360° around the axis of the grinding wheel, the profile shape is formed. This CAD method is simple and direct with accurate result. Finally, this method was illustrated in details in the forming grinding of helical flute of a rose cutter. This method can be applied to design of the profile of tools with any form manufactured by generating principle.

成型砂轮廓形设计的CAD法
将作图法和计算法相结合，提出成型砂轮廓形的CAD设计方法。该方法以啮合原理为根据，采用反求设计的思路；通过做一系列垂直于砂轮轴线的截面，得到相应的砂轮与螺旋槽的接触点，连接这些接触点得到接触线，将接触线绕砂轮轴线旋转360°，即是成型砂轮的廓形。该方法具有简单直观、结果准确的特点。以球头铣刀螺旋槽的成型磨削为实例，对用CAD法设计成型砂轮的过程进行说明。该方法可用于各种按展成原理进行加工的成型工具的轮廓设计。
