Abstract
FGH95 nickel-based superalloy is produced by powder metallurgy (PM) processing for aerospace applications. Due to lower thermal conductivity, work hardening tendency during machining, and intensive adhesion to the surface of the tooling under operation, machining of FGH95 alloy is a significant challenges. The FGH95 machining process will induce substantial amount of plastic deformation in the surface and subsurface of the workpiece. A theoretical model is developed to predict the plastic deformation in machined surface of FGH95 superalloy. Experimental results are also applied to analyze the influence of cutting speed on plastic deformation in machined surface of FGH95. It is found that cutting speed has significantly effect on the plastic deformation in the machined surface. The increasing the cutting speed creates severer plastic deformation. Surface plastic shear strain increases with the increases of cutting speed, while the depth of plastic deformation decreases contrary.
