ABSTRACT:
A streamlined method for the mass production of connecting rods is disclosed, with particular applicability for anticipated in the production of rods made from powdered metal materials. The method contemplates the rough grinding of a work piece, followed by the use of a single, flexibly tooled boring machine to create crank and pin bores. The work piece is then fracture split, subjected to a final grinding process and honed to specific tolerances without the need for final boring. The entire inventive process may be implemented on a five work station assembly line, thereby reducing the capital investment in machinery and space required by previously known methods.
