摘要： A method of sizing a cavity (21,121,221,321,421) in a part (20,120,220,320,420) includes forming the part having the cavity, including forming a plurality of protrusions (22,122,222,322,422) extending within the cavity (21...421) from at least one internal surface (23,123,223,323) of the cavity (21...421), the protrusions (22...422) having distal ends (22',122',222') bordering an unobstructed portion of the cavity (21...421), the unobstructed portion having an initial dimension (D MIN ) at least partially defined by a position of the distal ends (22',122',222'), pressing a deforming element (26,226,325) against the distal ends (22',122',222') of the protrusions to plastically deform the protrusions (22...422) toward the at least one internal surface (23,123,223,323) of the cavity (21...421) and increase the initial dimension (D MIN ) to a final dimension (D FIN ), and disengaging the deforming element (26,226,325) from the distal ends (22',122',222').
