If d=1, n=1 and f=4. Then find the value of m. d= diameter of drill in mm, n=rpm, f=feed per revolution in mm and m=metal removal rate in mm3/minute.

If d=1, n=1 and f=4. Then find the value of m. d= diameter of drill in mm, n=rpm, f=feed per revolution in mm and m=metal removal rate in mm3/minute. Correct Answer 0.3184

From the formula, m= (3.14*d*d*n*f) / 4. Here d,n and f are given. Substitute these values in above equation, you will easily get value of m as 0.3184 .
