Question
In orthogonal turning of low carbon steel pipe with
principal cutting edge angle of 90°, the main
cutting force is 1000 N and the feed force is
800 N. The shear angle is 25° and orthogonal rake
angle is zero. Employing Merchant's theory, the
ratio of friction force to normal force acting on the
cutting tool is
(a) 1.56
(b) 1.25
(d) 0.64
(c) 0.80
