The ground surface is the result of the
geometry interaction between grits and workpiece.
Therefore, its profile can be regarded as a reflection of
the upper envelope profile of effective cutting grains.
Based on that, a numerical method was proposed to
investigate the influences of abrasive wear height, cutting
depth and contacted belt length separately on surface
profile. According to the results of the application case, it
has been revealed that the abrasive wear height and the
contacted belt length had a significant effect on Ra of the
surface, while the cutting depth just affects Ra within a
