ULTRASONIC MACHINING. This method also takes advantage of graphite's special characteristics. Ultrasonic machining is also an abrasive process, but on a very different principle from the abrasive master process. The ultrasonic machining equipment is similar to the ultrasonic cleaning devices used to clean jewelry, small parts, etc.

An ultrasonic grating is a type of diffraction grating produced by the interference of ultrasonic waves in a medium, which alters the physical properties of the medium (and hence the refractive index) in a gridlike term acoustic grating is a more general term that includes operation at audible frequencies.. An ultrasonic wave is a sound wave at a frequency greater than 20 kHz.

Fewlayer (≤2 layers) graphene specimens were obtained by wet ball milling, heating in a nitrogen atmosphere, and solvent ultrasonic treatment. The ballmilling method was more effective than heating in a nitrogen atmosphere, and the [2 + 4] DA of graphene was more dominant than the [4 + 2] DA in the ballmilling process.

Rotary ultrasonic slot machining (RUSM) of ceramic matrix composites is explored. A comparison is made between RUSM and conventional diamond grinding by studying the effects of material removal rate (MRR) on process forces, tool wear and surface roughness. It was shown that RUSM leads to a significant decrease in process cutting forces and tool wear in comparison to the conventional machining ...
