The Effects of Cutting Conditions on Surface Integrity in Machining Inconel 718 Alloy

Abstract:

Machining of advancedaerospace materials have grown in the recent years although the hard-to-machinecharacteristics of alloys like titanium or nickel based alloys cause highercutting forces, rapid tool wear, and more heat generation. This paper presentsan experimental evaluation of machining of Inconel718 alloy under dry conditions at varying of cutting speeds and feed rates.The influence of the cutting conditions on surface integrity was studied interms of surface roughness, affected layer, grain size variations and phasechanges/modification. Also, the machining process performance was evaluatedthrough the power consumption and tool-wear.
