磨削过程可以看作是磨粒在砂轮表面不规则运动的微细切削过程。采用EASTEEdgeTM软件对AISI D2钢进行了宽切削参数范围内的单晶粒切削模拟。分析了切削参数对切削力、切屑形成和材料去除率的影响，并推导出了比切削力、临界切削深度和剪切角等切削参数。在切削区观察到切屑、侧毛刺和侧流的形成。材料去除率随切削深度和切削速度的增加而增加。比切削力随着切削深度的增加而减小，从而产生尺寸效应。剪切角随着切削深度和切削速度的增加而增加。采用这种单磨粒切削的析因分析方法，可以方便地计算磨削区中单个磨粒的切削力消耗。
The grinding process can be considered as micro-cutting processes with irregular abrasive grains on the surface of grinding wheel. Single grain cutting simulation of AISI D2 steel with a wide range of cutting parameters is carried out with AdvantEdgeTM. The effect of cutting parameters on cutting force, chip formation, material removal rate, and derived parameters such as the specific cutting force, critical depth of cut and shear angle is analyzed. The formation of chip, side burr and side flow is observed in the cutting zone. Material removal rate increases with the increase of depth of cut and cutting speed. Specific cutting force decreases with the increase of depth of cut resulting in size effect. The shear angle increases as the depth of cut and cutting speed increase. This factorial analysis of single grain cutting is adopted to facilitate the calculation of force consumption for each single abrasive grain in the grinding zone.
