Abstract

Numerous aluminium alloys are suitable for cutting. The alloy of the type AIMgSiPbBi is used for free cutting. For free cutting, lead and bismuth are added to the alloy since they improve chip breaking and thus material machinability. Considering that the technology has to be adapted to the use of HSS tools, the research was focused in this direction. In addition to the basic machinability investigations, research was done also into the effects of deformation zone in cutting using Quick Stop Device (QSD). A relationship between the chip shrinkage ratio λ and shear angle φ was established. Both indicators are significant in assesing machinability af Al-alloys and can be included into the process technology database.
