Ultrasonic machining, also called ultrasonic drilling, is a subtractive fabrication process that uses high-frequency vibrations and abrasive particles to remove small amounts of material from a workpiece's surface.It is ideal for glass fabrication operations, as it removes surface material very slowly without compromising the substrate's crystalline structure.
Ultrasonic assisted grinding (UAG) is one of the most suitable methods for the processing of hard and brittle materials such as silicon carbide (SiC). During UAG of SiC, the machining quality is directly determined by the material removal mechanism. However, the research on the material removal mechanism for UAG of SiC is still not sufficiently developed. …
