railway RRB JE (CBT I + CBT II) Mock Test 2024 Production Engineering (Manufacturing) Machining Processes and Machine Tools Tool Signature
In orthogonal machining using tool with 6° rake angle,
Cutting speed = 60 m/min, Width of cut = 3 mm, Depth of cut = 1 mm, Chip thickness = 1.5 mm,
Assuming shearing takes place at minimum energy condition, chip velocity = ? m/min1
