A simulation of abrasive belt grinding process was carried out. In abrasive belt grinding, the height distribution of grain cutting edges changes with the advance of grinding time and the elastic deformation of contact wheel is the cause of the displacement of grain cutting edge position. So, the influence of the height distribution and elastic displacement of the grain cutting edges were investigated by the simulation. As a result of that, the mechanism of residual depth of cut and the finished surface roughness were analyzed theoretically in cylindrical plunge grinding. The obtained main results are as follows. (1) Residual depth of cut and finished surface roughness increase as the height distribution of grain cutting edges becomes wide. (2) In the case of using a rubber contact wheel, the displacement of grain cutting edges makes the residual depth of cut increased. But, the increase of effective cutting edges makes the finished surface roughness improved. (3) Residual depth of cut caused by the height distribution and displacement of the grain cutting edges is almost generated at the start of grinding. (4) It was found that there is an optimum rubber hardness of contact wheel.
