摘要：
Machining of advanced aerospace materials have grown in the recent years although the hard-to-machine characteristics of alloys like titanium or nickel based alloys cause higher cutting forces, rapid tool wear, and more heat generation. This paper presents an experimental evaluation of machining of Inconel 718 alloy under dry conditions at varying of cutting speeds and feed rates. The influence of the cutting conditions on surface integrity was studied in terms of surface roughness, affected layer, grain size variations and phase changes/modification. Also, the machining process performance was evaluated through the power consumption and tool-wear.
