Question
Orthogonal turning of a mild steel tube with a tool of rake angle is carried out at a feed of . If the thickness of the chip produced is , the values of shear angle and shear strain will be respectively
Correct answer
(A) 28²⁰' and 2.19
Solution
Given:
Rake angle () =
Uncut chip thickness () = feed =
Chip thickness () =
Rake angle () =
Uncut chip thickness () = feed =
Chip thickness () =
1.Calculate chip thickness ratio ():
2.Calculate shear angle ():
3.Calculate shear strain ():
Thus, the values are and . Correct option is (A).Continue learning with Success Tracker
