Microultrasonic machining is a feasible solution for development of complex shapes at microlevels. Production of parts in microscale, especially with brittle materials, is challenging. In micro-USM, the volume of material removed per stroke is very little due to the use of micrometer size abrasive particles. Micro ultrasonic machining (MUSM) is a method derived from conventional ultrasonic machining, in which a tool and free abrasives are used. The motion of the tool takes place vertically or orthogonal to the surface of the part. The, thermal energy liberated by spark discharges over the work material results in mate-, rial removal due to melting and vaporization [, Nonequilibrium Quantum Dynamics of Biomolecular Excitons. The microtool is then mounted on a custom-designed setup for batch mode micro ultrasonic machining (µUSM) of a workpiece to make the desired pattern.
