Abstract
An initially separate blank and pin, where the blank one is formed of powdered metal, and is joined to the pin compressing and locally densifying the blank so that a deviation from perpendicularity of the joined pin to the blank is less than or equal to approximately 0.00120" at a distance of approximately 0.4" from a planar first surface. In accordance with a further embodiment, the blank is formed of powder metal and is joined to the pin by compressing the blank so that for a process limit of approximately 0.00120" at a distance of approximately 0.4" from a planar first surface, a capability index of the joined pin to the blank is greater than or equal to approximately 2.00.
