railway RRB JE (CBT I + CBT II) Mock Test 2024 Production Engineering (Manufacturing) Machining Processes and Machine Tools Machining Analysis
During orthogonal machining with an HSS tool, the rake angle was 5°, the un-deformed chip thickness was 0.25 mm and the width of the cut was 4 mm. The coefficient of friction was 0.5. Find the value of the shear angle. use (tan-10.5) = 26.56°
