Grinding ratio is defined as ratio of Volume of work material removed to the ratio of wheel material removed.

=\;{\;\text " Volume of work material removed "\;(V_{m})}/{\;\text " Volume of wheel "\; wear(V_{w})}

200=\;{\;\text " Volume of work material removed "\;(V_{m})}/{\;\text " Volume of wheel "\; wear(V_{w})}

Grinding wheel wears
