The Evaluation of Tool Wears in Machining of SiCp/Al Composites

In this paper an experimental study in milling of SiCp/Al composites on a high precision machine was carried out by using TiN coated tools, TiAlN coated tools and carbide tools. The result of tool wear was observed and measured by an optical microscope and a scanning electron microscope (SEM). The results show that the main wear mode is the flank wear and the wear mechanism is abrasive wear and adhesive wear for the cutting tools used in the experiment.
