Surface Integrity Analysis on High Speed End Milling of 7075 Aluminum Alloy

Abstract

Surface integrity is a significant issue concerning machined part quality, especially for aluminum milling process in aerospace manufacturing. This paper gave an intensive analysis on surface integrity in high speed milling of 7075-T651 aluminum alloy, and the relationships of surface topography, surface roughness and residual stress profile with cutting speed at high levels were discussed and some basic aspects concerning surface integrity in high speed end milling of aluminum parts were presented.
