Grinding ratio is defined as ratio of Volume of work material removed to the ratio of wheel material removed.
Grinding wheel wears 1/200 (= 0.005) times the volume of material removed.
Grinding wheel wears 1/200 (= 0.005) times the volume of material removed.

Grinding Ratio:
The grinding ratio is a measure of the efficiency of the grinding process. It is defined as the ratio of the volume of material removed from the workpiece by the grinding wheel to the volume of the grinding wheel wear.
Explanation of options:
a) Grinding wheel wears 200 times the volume of the material removed: This option is incorrect because it implies that the grinding wheel wears more than the material removed, which is not possible.
b) Grinding wheel wears 0.005 times the volume of the material removed: This option is correct. A grinding ratio of 200 means that for every unit volume of material removed from the workpiece, the grinding wheel wears 0.005 units of volume. This implies that the grinding wheel wears much less than the material removed.
c) Aspect ratio of abrasive particles used in the grinding wheel is 200: This option is incorrect because the grinding ratio does not provide any information about the aspect ratio of the abrasive particles.
d) Ratio of volume of abrasive particle to that of grinding wheel is 200: This option is incorrect because the grinding ratio does not provide any information about the ratio of volume between the abrasive particles and the grinding wheel.
Conclusion:
The correct answer is option b) Grinding wheel wears 0.005 times the volume of the material removed. The grinding ratio of 200 indicates that the grinding wheel wears much less than the material removed during the grinding process.
