开发了一种数值模拟技术来生成使用方锥形磨粒的砂轮形貌。磨削后的工件表面也被生成，模拟所有磨粒的轨迹并去除干扰材料。计算了工件的平均表面粗糙度，研究了不同磨削参数对成形工件平均表面粗糙度的影响。最后，研究了表面粗糙度随最大未切屑厚度的变化规律。
A numerical simulation technique has been developed to generate the grinding wheel topography using square pyramidal grits. The ground workpiece surface has also been generated simulating the trajectory of all the abrasive grits and removing the interfering material. The average workpiece surface roughness is calculated and the effects of different grinding parameters on the average surface roughness of the generated workpiece have been studied. Finally, the variation of surface roughness with the maximum uncut chip thickness has been studied.
