Abstract:
1. A method for fabricating a valve mechanism component for combustion engines, comprising: extruding a billet of a metal matrix composite (MMC) material containing 10% to 70% ceramic material by volume in the form of particles of fibers into a bar that has a cross-sectional profile that essentially coincides with the desired cross-sectional profile of the fabricated valve mechanism component; obtaining separate billets for respective components by cross-cutting the bar by of cutting via high-speed machining, wherein said high-speed machining is characterized in that a very high power density is achieved in front of the cut and in that cutting forces tend asymptotically toward zero; machining the component into its final form by cutting via high-speed machining, HSM.
