Chapter 17: Grinding Methods and Machines Cutting Tool. G-ratio. The G-ratio is the ratio of the amount of stock removed versus the amount of wear on the wheel, measured in cubic inches per minute. This ratio will vary from 1.0 to 5.0 in very rough grinding, and up to 25.0 to 50.0 in finish grinding.get price

The term grinding ratio is defined as the ratio between the volume of metal removed from the workpiece to the wear of grinding wheel. If a graph is drawn between the wear of grinding wheel to the volume of metal removed then the tangent to the curve will represent the grinding ratio. ADVERTISEMENTS:

Generally, we need a very high reduction ratio to go from the run of mine to the liberation size. Therefore, it is necessary to divide the total R:1 into smaller ratios, thus it refers to multiple units of size reduction. The milling work is done in two circuits, crushing and grinding. The grinding reduction ratio is very higher than the crushing.

G-ratio in electroplated cBN grinding of AISI 52100 steel was found to be in the range of 5000–20000, whereas in grinding of difficult-to-cut materials, it varies from 10 to 300 [13,14]. Hence, it can be noted that wheel wear takes place at a faster rate while grinding difficult-to-cut materials as compared to steel.

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.
