Question

A grinding ratio of 200 implies that the

• A. grinding wheel wears 200 times the volume of the material removed
• B. grinding wheel wears 0.005 times the volume of the material removed
• C. aspect ratio of abrasive particles used in the grinding wheel is 200
• D. ratio of volume of abrasive particle to that of grinding wheel is 200

Answer 1

The correct option is B grinding wheel wears 0.005 times the volume of the material removed

Grinding ratio is defined as
$=\frac{\text{Volume of work material removed}(V_m}{\text{Volume of wheel wear}\left(V_w\right)}$

$200=\frac{\text{Volume of work material removed}(V_m}{\text{Volume of wheel wear}\left(V_w\right)}$

Grinding wheel wears 0.005 times the volume of material removed.
