- Grinding involves an Abrasive action and while removing material abrasive also wears out and when the rubbing force reaches the threshold, the worn-out abrasives are pulled out of the wheel.
- Thereby giving chance to a fresh layer of abrasives for removing material. This is known as the self-sharpening behavior of the grinding wheel.
- The ratio of the volume of material removed to the volume of wheel wear is known as grinding ratio.
\(Grinding\;ratio = \frac{{{V_m}}}{{{V_w}}} = \frac{{l \times b \times d}}{{\frac{\pi }{4} \times w \times \left( {D_i^2 - D_f^2} \right)}},\;where\;w = width\;of\;wheel\)
- The grinding ratio varies from 1.0 - 5.0 in very rough grinding.
