Abstract
A method of joining multiple powder metal components to form a powder metal component assembly using an adhesive is disclosed. By machining at least one of the powder metal components prior to the adhesive joining, otherwise difficult to machine features can be more easily machined for less cost and at higher production rates. Unlike high temperature joining techniques, the adhesive joins the powder metal components at room temperature. This room temperature adhesive joining eliminates the thermal distortions in pre-joined machined features common to high temperature joining techniques such as brazing or welding that bring these features out of specification during joining.
