Using the simulation and statistical techniques, Liao et al. [14] determined the size distribution of grinding-induced cracks to ceramic materials and predicted the crack size ranging from 3 to 37 μm for alumina subjected to creep feed grinding. They then suggested that in order to alleviate subsurface damage, finer wheels should be used.

Fig. 6 shows the changes of diamond wheel topographies during ultrasonic vibration-assisted grinding alumina ceramic after 200, 400, and 600 passes. From the change of wheel surface, one can find that the diamond grits appear to be higher protrusion (grit 1), fracture (grit 2), or pull-out (grit 3). At the meantime, with the wear of metal bond ...
