Abstract:

Hot machining can reduce the cost of manufacturing parts from heat treated 4340 and Ph 15-7 Mo steels up to 36 when compared to conventional machining. The cost of machining a heat treated 4340 main landing gear truck pivot was reduced from 24.85 to 18.69 and the cost of milling a Ph 15-7 Mo extrusion was reduced from 2.00 per foot to 1.27 per foot when elevated temperature machining was applied. Rene 41 does not respond to hot machining when workpieces greater than 2 wide are face milled. Author
