[#241] In orthogonal turning of a low carbon steel bar of diameter 150 mm with uncoated carbide tool, the cutting velocity is 90 m/min. The feed is 0.24 mm/rev and the depth of cut is 2 mm. The chip thickness obtained is 0.48 mm. If the orthogonal rake angle is zero and the principle cutting edge angle is 90°, the shear angle in degree is
Correct Answer
(B) 26.56
[#242] The lip angle is the angle
Correct Answer
(A) Between the tool face and the ground end surface of flank
[#243] The tool material, for faster machining, should have
Correct Answer
(D) All of these
[#244] A grinding wheel is said to be of _________ if it holds the abrasive grains more securely.
Correct Answer
(C) Hard grade
[#245] Flank wear depends upon the
Correct Answer
(B) Amount and distribution of hard constituents in the work material
Explanation
Solution: Flank wear occurs on the relief (flank) face of the tool.
Flank wear occurs as a result of friction between the progressively increasing contact area on the tool flank.
