ABSTRACT:
unidirectional abrasive flow machining is achieved by a pair of extrusion chambers, whereby a first workpiece is fixtured to a first of said chambers and an abrasive medium is extruded from the first chamber through the first workpiece, and upon exiting the first workpiece, is allowed to fall into and be collected within the second chamber. Thereafter, the first workpiece is removed and a second workpiece is fixtured to the second chamber so that the abrasive medium collected therein is extruded through the second workpiece and upon exiting the second workpiece, is allowed to fall into and be collected within the first chamber.
