This type of MMC material is typically called whisker reinforced aluminum. This material is used in application where light weight and great stiffness is required. Machining this material can be performed using poly crystalline diamond as per firedog but it can also be cut using EDM or wire EDM or grinding. I assume ECM could also be used. I personally have no experience machining this material but a friend of mine related his experience to me and I researched the material. The friend was machining parts of an inertial guidance system for a satellite or a missile. |
