Abstract

The invention relates to an apparatus and process for machining a rotating workpiece by means of rotary ultrasonic grinding. The apparatus performs rotary ultrasonic grinding by rotating and vibrating a surface finishing tool in contact with a rotating workpiece. The rotary ultrasonic grinding process is a hybridized method which comprises a combination of conventional ultrasonic machining and diamond grinding. Important parameters in one embodiment of the process include ultrasonic vibration amplitude and frequency, static pressure or force, tool rotation speed, workpiece rotation speed, grit size, grit concentration, abrasive type, and bond type.
