ABSTRACT:
Elongated generally rectangular in-section conductive metal bar stock is formed by extrusion to form a post type electrical bus connector. The shorter dimension is approximately the diameter of the posts to be formed, while the longer dimension is approximately the height of the posts plus the thickness of the bus or bar from which the posts will project. The narrow end forming the bus has a triangular ridge. The bar stock is cut-to-length dictated by the number of posts to form blocks which are then loaded into specialized pallets of a machining center. The machining center is the type having at lest two pallets, one being loaded while the other is indexed with respect to the tool spindle. The machining center also includes an automatic tool changer. The machining center mills the posts with a hollow center flush mill, drills the hole in the posts and forms tapped holes followed by deburring. The bar stock may have extruded L-shape flats, one of which forms a pad for a compression type connector. In the manufacture of such compression connectors, the drilling of a hole axially of the posts is not required.
