Investigation of Process Responses in Rotary Ultrasonic Machining of Al/SiC Composite Through Designed Experiments

In production-based trades, Al/SiC composite is vastly required owing to its outstanding possessions. Though, the problems in its machining confine the application and attractiveness of this material. Present study focused on different experimental conditions (spindle speed, rate of feed, and ultrasonic power) on responses of interest like surface roughness (SR), material removal rate (MRR), and chipping thickness in rotary ultrasonic machining of Al/SiC composite. Microstructure scrutiny of the processed samples has been employed to illustrate the chipping size and thickness over the end-edge through SEM process. The experimental results showed that rate of feed was the most significant variable for MRR and SR.
