Electrochemical Machining and Its Use in Finishing of Electrodischarge Machined Dies
Dies and molds are now commonly produced by electrodischarge
machining (EOM), the sparks in the process eroding
metal preferentially from the component, such that its shape
gradually becomes complementary to that of the tool electrode.
Although EOM is slow, the accuracy with which complex shaped
products can be manufactured by this process readily to 0.01 mm
tolerance – makes it increasingly attractive in manufacturing
industry.
