The turning test was carried out under the dry cutting condition to evaluate the machinability of aluminum alloys (Al-5.6mass%Cu-4.0mass%Si) which aged up to several stages, as a candidate of the free-cutting aluminum alloy without lead. The chip breaking during turning were low in the under-aged alloys, but that were increased in the over-aged alloys. The chip breaking of the most over-aged alloys was equal to that of the free-cutting aluminum alloy with lead. The changing of the chip breaking by aging treatment for the alloys was closely related to generation of the adhesion on the cutting tool. Although the increase of the adhesion caused increasing the chip breaking, that also caused roughing of machined surface.
