using an axially oscillating tool at ultrasonic (US) frequency (18–20 kHz).
During that oscillation, the abrasive slurry of B

C or SiC is continuously fed
into the machining zone, between a soft tool (brass or steel) and the work-
piece. The abrasive particles are, therefore, hammered into the workpiece
