EDM Conquers Copper

摘要

Peak performance to an EDMer usually means high metal-removal rate (mrr) combined with little or no electrode wear. This combination is easy to achieve when die-sinking a work metal such as a tool steel or a stainless steel. Metal removal is fast, and the graphite electrode is subjected to virtually no wear. Good results can be achieved using a wide range of operating parameters. However, there are some work metals that are very difficult to EDM, making the selection of operating parameters critical to success.
