Abstract: Surface milling of a multiaxial [(45/90/135/0)16]s carbon fibre reinforced plastic was investigated experimentally. A comparison between 19° and 60° lead angle tool are related in this study. The aim was to compare the cutting behaviour of a 19° and a 60° lead angle tool. Several points of comparison have been chosen such like cutting force, material temperature, milled surface roughness, delamination and tool wear. A wide range of cutting conditions was tested with a depth of cut equals to four plies in order to minimise the influence of plies orientation. This previous factor has been widely describe in the literature. Cutting results with 19° lead angle have shown reducing in cutting force, less wear and less delamination in comparison with 60° this results are partly explained by the insert geometry.
