During an orthogonal machining process shear force and shear velocity was calculated as 300 N and 140 m/min respectively. The shear energy completely appears as heat and 90% of which travels with the chip while 10% flows to the work piece. The average temperature at shear plane (in °C) is
Pmaterial = 2700 kg/m3; undeformed chip thickness = 0.7 mm
Width of cut = 2 mm; specific heat of material is 500 J/kgK
Cutting velocity = 200 m/min; environment temperature = 25°C
  • a)
    100
  • b)
    125
  • c)
    185
  • d)
    220
Correct answer is option 'B'. Can you explain this answer?

During an orthogonal machining process shear force and shear velocity...
Fs = 300 N; Vs = 140 m/min; K = 0.9; t = 0.7 mm
ρ = 2700 kg/m3; b = 2 mm; Cp = 500 J/kgK Vc = 200 m/min = 3.34 m/s
Equating amount of heat received by chip from the shear zone and the heat contained by chip KFsVs = Cp(bt)V(Ts — T0)
