5. Types of Grinding Wheel Machines and their outputs. (atleast 3)
11) An internal bore is ground to 100 mm, removing 0.3 mm stock. To accomplish
this, a grinding wheel 80% of the finished size is used. The wheel is dressed every
15 cycles because it is observed that the radial wheel wear is 0.05 mm on average.
Assume wheel and part widths are equal.
a. What dressing depth would you recommend and why?
b. Calculate the G-ratio of this operation.
Define trueing and creep feed grinding.
