GATE 2025 PI – Question 30
Manufacturing Processes II · Machining · 1 mark · Numerical answer
In orthogonal straight turning, feed is 0.1 mm/rev and cut depth is 0.5 mm. ASA side cutting-edge angle is 0°. Find chip width (one decimal mm).

Show answer and explanation
Correct answer: 0.5 to 0.5
Explanation
The undeformed chip width is $b=d/\cos C_s$. With side cutting-edge angle zero, $b=0.5/1=\mathbf{0.5}$ mm. Feed sets chip thickness instead.
