railway RRB JE (CBT I + CBT II) Mock Test 2024 Production Engineering (Manufacturing) Machining Processes and Machine Tools Machining Analysis
The relationship between the shear angle ϕ, friction angle β, and cutting rake angle α, and the machining constant C for the work material is
1
2ϕ + β - α = C
2
2α + β - ϕ = C
3
2β + α - ϕ = C
4
2ϕ + α + β = C
