Hot Drilling of Aluminium Matrix Composite

Abstract:

The aim of this paper is to investigate the behaviour in terms of drilling forces and roughness of Metal Matrix Composites (MMC) in hot drilling machining. In particular, Al2009/(SiC)_w, Al6061/(SiC)_w, and Al6061(Al₂O₃)_p metal matrix composites were used, and the adopted temperature were in the range 20°C-160°C. A comparison with drilling at room temperature has been discussed. The results have shown the sensible influence of the working temperature on drilling forces and on surface material properties. In the case of Al2009/(SiC)_w a minimum in the drilling forces has been found, making possible the dry machining and improving the cutting conditions. Instead, for Al6061/(SiC)_W and Al6061(Al₂O₃)_p in the used temperature range no minimum appears.
