ABSTRACT:
A method for fabricating components such as rocker arms (4), cam followers (3) or cams for valve mechanisms for combustion engines, in which a billet of an MMC material (Metal Matrix Composite) containing 10–70% ceramic material by volume in the form of particles or fibers is extruded into a bar (1, 2) having the cross-sectional profile of the final component (3, 4), and where separate billets for the respective components (3, 4) are obtained by cross-cutting the bar (1, 2) by means of cutting via high-speed machining, HSM.
