Self-sharpening tooling design for ultrasonic impact grinding of cmcs

A method of ultrasonic impact grinding comprising:

• applying longitudinal vibration to a tip of a tool in the direction of an axis of the tool;
• impacting a substrate with the tip;
• supplying an abrasive slurry to a terminal end of the tip;
• and
• evacuating the abrasive slurry and debris from the terminal end of the tip;
• wherein the abrasive slurry is supplied through a bore extending longitudinally through the tool or the abrasive slurry and debris is evacuated through the bore extending longitudinally through the tool.
