Question:-
An orthogonal cutting operation is being carried out under the following conditions : cutting speed = 2m/s, depth of cut = 0.5mm, chip thickness = 0.6mm. Then the chip velocity is
Option (A)
2.0m/s
Option (B)
2.4m/s
Option(C)
1.0m/s
Option(D)
1.66m/s
Correct Option:
(D)
Question Solution:
r = (Uncut chip thickness / Chip thickness) = (tc/t) = (0.5/0.6)
\ Velocity of chip = Vc x r = 2 x (0.5/0.6)
= 1.66 m/sec.
