An orthogonal machining operation removes metal at 1.8 in3 /min. The cutting force in the process = 300 lb. The work material has a thermal diffusivity = 0.18 in2 /sec and a volumetric specific heat = 124 in-lb/in3 -F. If the feed f = to = 0.010 in and width of cut = 0.100 in, use the Cook formula to compute the cutting temperature in the operation given that ambient temperature = 70°F.
