The tool life equation for HSS tool is VT^0.14f^0.7d^0.4 = Constant. The tool life (T) of 30 min is obtained using the following cutting conditions: V = 45 m/min, f = 0.35 mm, d = 2.0 mm. If speed (V), feed (f) and depth of cut (d) are increased individually by 25%, the tool life (in min) is

A

0.15

B

1.06

C

22.50

D

30.0

Correct : b
