ABSTRACT:
Manufacture of a fluid connector fitting from an elongate metal stock, such as a plate or barstock, or a billet having an indefinite length and the potential for one or more centerline inhomogeneities which may extend along a longitudinal central axis thereof. In one embodiment, a metal stock is provided as having a cross-section of a first dimension which may be at least about equal to the extent of a first or second widthwise extent of the fitting and a second dimension which is at least about twice the extent of the other widthwise extent of the fitting. The stock is sectioned through the second dimension thereof along its longitudinal central axis to equally divide it into at least first and second workpieces. Each of the workpieces extends along a corresponding longitudinal axis thereof and has a cross-section of a first and a second width which may correspond, respectively, to the first and second widthwise extents of the fitting. In another embodiment, a billet is provided for forming an elongate barstock of a given cross-section and an indefinite length. The billet is sectioned through a central axis thereof into at least four workpieces of about equal cross-sections each having first and second sectioned surfaces which intersect to define an edge portion within which the potential inhomogeneities are localized. At least one workpieces is chamfered to remove the edge portion therefrom, and then is worked to form the barstock.
