利用计算机数字模拟技术作为手段分析研究磨粒尺寸大小及形状对磨削加工过程和被磨例表面的影响。结果得出磨粒粒径大小影响到砂轮表层的磨粒中实际参加切削的磨粒数目，磨粒粒径越小，被加工表面粗糙度越小。由大大小小不同粒径磨粒构成的砂轮与单一粒径磨粒的砂轮相比，其被加工表面粗糙度要小得多。唐粒几何形状和磨粒表面微观粗糙度对被加工表面粗糙度影响不大。
Using computer numerical simulation technology as a means to analyze the impact of abrasive size and shape on the grinding process and the surface being abraded. The result shows that the particle size of the abrasive particles affects the actual number of abrasive particles in the abrasive particles on the surface of the grinding wheel. The smaller the particle size of the abrasive particles, the smaller the surface roughness to be machined. Grinding wheels made of abrasive grains of different sizes, large and small, have a much smaller surface roughness than grinding wheels of a single grain size. Tang grain geometry and abrasive surface roughness of the surface roughness is not affected.
