Aluminum metal matrix composites are widely used in various engineering
areas due to their excellent mechanical properties. However, due to their
heterogeneous structure, efficient machining of these materials is still a
challenging task. Therefore, in the present study the drilling performance
of aluminium-copper alloy (Al 2024) reinforced with SiC nanoparticles
was experimentally investigated, in the presence of ultrasonic vibration.In
this regard, the influence of ultrasonic vibration, SiC weight fraction and
drilling parameters was assessed on circularity error and drilling thrust
force. Also, the optimization of process parameters was investigated using
grey relational analysis. The performed calculations revealed that
ultrasonic vibration, SiC content of 2 %wt, feed rate of 20 mm/min and
spindle speed of 1400 rpm is the optimal parameters setting in the present
study.
