PURPOSE: A method and apparatus for abrading the region of intersection between a branch outlet and a passageway in a body is provided to abrade the region of intersection by using abrasive flow machining. CONSTITUTION: For a body(10) having a wall with an inner surface(40) along a passageway(11) and at least one branch outlet(15) defined by an opening extending through the wall, a method of abrading the inner surface at an intersection region(35) defined by the intersection of the periphery of the opening at the body wall comprises the steps of: positioning a first media delivery tube within a first end of the passageway, wherein the first tube has an inlet and an outlet and wherein the outlet is proximate to the periphery of the opening; supplying a flowable abrasive media through the inlet of the first tube to the outlet; and guiding the media from the outlet of the first tube through the opening.
