specific energy requirements in a grinding process are more than those in turning for the same metal removal rate because of the
Option (A)
Specific pressures between wheel and work being high
Option (B)
Size effect of the large contact areas between wheel and work
High cutting velocities
High heat produced during grinding
Correct Option:
Question Solution:
Grinding process is a very inefficient one compared to the conventional metal cutting process.
Specific energy of grinding = 50J/mm3 Specific energy of other = 2 to 5J/mm3
A large number of cutting edges are involved in cutting this result in large contact area wheel and work
