ABSTRACT:
A method of machining metal-matrix composite materials using electrochemical machining is provided. The method comprises the steps of: providing a metal matrix composite material in an electrochemical machine, and electrochemically machining the metal-matrix composite material in a nitrate or chloride containing electrolyte at a current density of equal to or greater than approximately 1 A/cm.sup.2. Preferably the metal-matrix composite is comprised of an aluminum alloy or pure Al matrix with ceramic particles, such as silicon carbide.
