G-Ratio - an overview | ScienceDirect Topics

2012-3-3 · G = 0.040 × 1000 / 0.001 × 3.142 × 170 = 74.9. High G ratios may be in excess of 5000 whereas for a difficult-to-grind material, the G ratio may be as low as 1. Dressing a grinding wheel causes a further loss of the abrasive layer. In the evaluation of the life of the wheel it is necessary to take this into account.
