Abstract:
A method of attaching and adjusting first and second members includes providing a first member having an outer surface and a second member. The second member is affixed to
the outer surface of the first member at a desired axial position along the length of the first member and in a desired angular orientation. Subsequent to affixing the
second member to the first member, the shape and/or dimensions of the second member is adjusted by increasing the density of at least a region of the second member. The
densification may be accomplished by, for example, a mechanical working technique such roller burnishing, coining, sizing, shot peening, or laser impacting. In one
embodiment of the invention, the method may is adapted to the production of combustion engine camshafts from separately provided camshaft tubes and cam lobes.
