Abstract
A component made from a material of metal matrix composite, a so-called MMC material, is manufactured by High Speed Machining, so-called HSM machining, of a workpiece or blank of MMC material to provide a predetermined shape. HSM machining is characterized in that the cutting tool operates at a very high speed in relation to the machined work piece, especially as compared to what is normally the case when using conventional machining techniques.
Claims15
A method for manufacturing a component having a predetermined shape from a metal matrix composite material, the method comprising:
- machining with a cutting tool comprising a cutting edge a blank of the metal matrix composite material comprising 15% to 70% reinforcing content by high speed machining in which shearing forces are decreasing with increasing cutting speed, the machining being effective to obtain the predetermined shape of the component.
