Considering this, the protocol of grinding (i.e. grinding tool, grit-size of grinding instrument, presence/absence of cooling, pressure during grinding) may play an important role on this outcome. Therefore, a systematic review may be a helpful tool to clarify the effects of this mechanism and to guide future studies on this topic.

Mechanism of ductile/ shear mode grinding of brittle materials The ductile surface is the result of material removal due to shearing, where the material is planed off at a micro scale level. In the ductile mode, the energy is transferred into a permanent deformation of the work piece material; in contrast, in the brittle mode, more machining ...

The results indicate that as the number of grinding passes increases, a decrease in the grinding force reduces both the amount of removed rail material and the surface roughness. There is a decrease in the grinding ratio caused by the increase in the wear on the grinding wheel and the decreased removal of the rail material.
