Abstract

In this paper micro end milling tests were carried out in a fine grain aluminium alloy (RSA 6061-T6 – Average grain size of 1 um). Results showed that the mean cutting force (Fc) varied in the range of 180 mN up to 400 mN for both cutting tools. Smaller cutting forces were probed for the cutting tool with the smallest cutting edge radius. The surface roughness presented better results for the tool with the largest cutting edge radius and the smallest feed per tooth condition and it was 0.17 ?m Rq. The specific cutting force was estimated 364 N/mm 2 and the constant z =0.27.
