Abstract

The current study aims to describe the experimental examination and ultrasonic machinability behavior of the titanium composite, which is synthesized by a casting technique. Tungsten carbide (WC) works as reinforcing particles and adds 6% of the titanium alloy's weight. Material properties, characterization, and alloy composition are examined by mechanical testing, scanning electron microscopy (SEM), and energy dispersive x-ray analysis (EDAX), respectively. Rate of metal removal (RMR) and surface finish (SF) are evaluated by the variation of ultrasonic machining (USM) input constraints such as power rating, slurry concentration, and grit size. Ultrasonic machining parameters and desired responses are optimized using the Taguchi technique. The ultrasonically machined surface and its microstructural analysis are investigated using atomic force microscopy (AFM). The desirable RMR was attained at a power rating of 450 W, a 20% slurry concentration, and a grit size of 400. Surface finish was reached at a power rating of 150 W, 15% slurry concentration, and grit size of 400
