Question
A grinding ratio of 200 implies that the
Options :
grinding wheel wears 200 times the volume of the material removed
grinding wheel wears 0.005 times the volume of the material removed
aspect ratio of abrasive particles used in the grinding wheel is 200
ratio of volume of abrasive particle to that of grinding wheel is 200
Answer :
grinding wheel wears 0.005 times the volume of the material removed
Solution :
Grinding ratio is defined as ratio of Volume of work material removed to the ratio of wheel material removed.
= Volume of work material removed( Vm)/ Volume of wheel wear( Vw)
200 = Volume of work material removed( Vm)/ Volume of wheel wear( Vw)
Grinding wheel wears 1/200 (= 0.005) times the volume of material removed.
