Abstract
The general machining characteristics of three aluminium-silicon pressure-die-cast alloys are listed and discussed. Recommendations are made for maintenance of tool life and avoidance of built-up edges or adhesive welded particles. Cast surface quality and influence of other casting defects are considered and illustrated. The influence of silicon content, porosity and multiple cut interruption on tool life was studied. For machining of hypereutectic aluminium alloys with high silicon content a limit for the applicable cutting speed was found: the point of thermal overloading of the work material in the shear zone by means of a deceptive chip formation.
