Fan et.al [8] has presented a particle image velocipede- try (PIV) technique to study the particle velocity in micro abrasive jet machine. He found that particle jet flow has linearly expansion in downstream. Due to the increase in air pressure the particle velocity increases. He considered radial profile and axial in the particle flow field.

Abrasive jet machining (AJM), similar to sand blasting, is a flexible microfabrication process, using high-velocity abrasive jets to remove excessive materials from a hard workpiece by impact erosion [81–83].Unlike bonded abrasives in micro-grinding, micro-abrasives in AJM are carried by water/air jets, which offers higher flexibility, lower contact force, and less thermal damage …
The basic machining principle of MAJM (micro-abrasive jet machining) is shown in Fig. 1.In the process, micro-abrasives (tens of μm), accelerated by highly compressed air or gases, are forced through a micro-nozzle, and collide with hard and brittle workpieces at a very high velocity (80–200. m/s) and density.. Since the material removing process of MAJM is …

Therefore, the increase of surface micro-patterning resolution presents an interest in several industries. Liquid-based abrasive jet polishing has lower MRR than AAJM but provides better surface roughness. With an eye to combine both advantages, an attempt to build a bridge between air and water-based abrasive jet systems was presented as CAAJM.
