US Patent for Abrasive flow machining with an in situ

Abrasive flow machining is a well known nontraditional machining process whereby a visco-elastic medium, permeated with an abrasive grit, is extruded through or past a workpiece surface to effect an abrasive working of that surface. The abrasive action in abrasive flow machining can be thought of as analogous to a filing, grinding, lapping or

Abrasive flow machining Wikipedia

Abrasive flow machining (AFM), also known as abrasive flow deburring or extrude honing, is an interior surface finishing process characterized by flowing an abrasive-laden fluid through a workpiece. This fluid is typically very viscous, having the consistency of putty, or dough. AFM smooths and finishes rough surfaces, and is specifically used to remove burrs, polish surfaces, form radii, and even remove material. The nature of AFM makes it ideal for interior surfaces, slots, holes, cavities, and other areas that may b
