ABSTRACT:
Method and Tooling for removing material from holes or orifices (round or other shapes) or the like in a workpiece, the method and tooling providing means for directing at least a first portion of an abrasive flow composition under pressure from a main body of composition from one side of a workpiece to another side of the workpiece (i.e. about the workpiece) so as to permit at least a second portion of the abrasive flow composition also under pressure from the same main body of composition to easily flow through the holes therein. In the preferred embodiment a first portion of the composition which is directed about the workpiece is returned to a point adjacent another side of the workpiece and is directed at an angle to the flow of the second portion of the composition through the holes in order to produce an interaction between the flow of said first and second portions of said composition.
