| Abstract: | Grinding damage, typically in the form of micro- and macroscopic cracks, chipping, voids, etc, is not normally preferred and should be avoided for structural components made of fine ceramics. This paper deals with grinding damage in fine ceramics. It gives a review on "ductile-regime"--the energy principle in grinding of fine ceramics, and analyzes the "pros" and "cons"of"ductile-regime"grinding. Theoretical and experimental evidences on grinding damage that goes beyond "ductile-regime"are also provided. |
