Abstract
A finite element analysis of end milling a nickel-base superalloy is presented for aiming at understanding its cutting performances, and improving cutting conditions, cutting efficiency and machined surface integrity. A formulation coupled with radial return method for thermo-elastic plastic finite element method, penalty methods, mass scaling, subcycling gave chip formation and cuttig processes of Inconel718. Calculated and experimental results on. end milling of S45C with HSS tool agreed well in cutting forces and shapes of chip. From calculated results on end milling of Inconel718, it was found that cutting speed had a great influence on the cutting temperature on the rake face.
