Abstract
A method of manufacturing a component formed of parts capable of being separated for reassembly around another component. The process starts by taking separate, e.g., rod and cap, forgings and coining or forging them together prior to machining. The mating surfaces of the forgings are formed with a ridge-groove or a dimple/lug-recess configuration giving them a self-locating ability. After machining, the forgings are fractured along the original division to obtain two uniquely matched surfaces that need no further processing before being reassembled, e.g., to form a connecting rod for an internal combustion engine.
