The Grinding Ratio ($G$) is a crucial indicator of grinding process efficiency. It is defined as the ratio of the volume of material removed from the workpiece to the volume of grinding wheel material worn away during the operation. This means:
$G = \frac{\text{Volume of work material removed}}{\text{Volume of wheel wear}}$
A higher grinding ratio signifies better efficiency, as more workpiece material is removed for less wheel wear.
