The term "milling" refers to the manufacturing process of using a circular cutting tool on the ends and sides of a material blank to make a finished part. That's obviously just a very general summation; there are actually around 30 different types of milling operations, 15 of which (the most commonly used ones) we'll go over in this article.

However, the graphite's microstructure is often the limiting factor in how the electrode performs during final EDM operations. In a different article for MMT, Mercer says flexural strength should be above 13,000 psi to ensure graphite machinability into deep, thin ribs without breakage.
